- In the Ashton Graybiel Spatial Orientation Laboratory at Brandeis University, there's the Artificial Gravity Facility: otherwise known as the rotating room. No-one's invented futuristic gravity plating yet, but if you want to test how humans would cope with artificial gravity, this is the best way.

I held this video back by a day, because putting out a serious video on April 1st is a fool's errand.
Yes Scott my guy
Worth the wait.
Smart move.
Yah
Especially if the video is about a room that looks like it makes physics break. Could have made a great 2 parter, though.
I would’ve lost it if Tom went for the handshake at the end and overshot it by 90 degrees LMAO
I was expecting something to happen, i'm disappointed.
I was about to comment the same thing
I was afraid he'd accidentally slap the guy in the face
@@segnido and miss that too by 90 degrees.
@@segnido *hoping
I love Tom’s childlike outbursts of pure joy as his brain struggles to understand the wrong-seeming stimuli being fed to it, and just doesn’t quite know how to react.
That sounds really psychopathic, sorry
@@kidzvidz3262 It really doesn't. That word doesn't mean what you think it means.
I find those little outbursts so incredibly endearing!
"I am very smart"
The way you word it makes it seem like you're trying too hard to sound smart.
That last part about muscle memory was interesting. It reminded me of when somebody showed me this trick where you stand in a door frame and you push out and then when you take a step forward your arms continue to push out even though you’re not pushing anymore.
what, what do you mean
@@lrizzard if you go to any doorframe and push on it with the outsides of your palms for about a minutes as hard as you can, your hands will want to rise into the air despite you leaving the doorframe and no longer wanting to push up
One of my favourite little tricks my parents showed me when I was a kid!
@@theonlysamman3889 cool brain trick,i just remembered one from my school. Push hard two pen against each other and when you try to separate them slowly,you will feel as if the pen had a magnet. Compare to when you don't push them as hard
I wonder if its the same as like when you're on a boat or in a wave pool for an extended period of time and once you're standing on solid ground it feels like your body is still moving to the waves
It's amazing how quickly the human brain adapts to alien scenarios. We really are badass supercomputers, each and every one of us.

@@rogerstoned2592It's because you as a human limit yourself. You can do anything. It just takes strict discipline and most give up before they can succeed because they never truly wanted what they were searching for.

@secondsquirrel1168 that's what people have said in the past until someone proved them wrongs
If everyone is a badass supercomputer, nobody is.
I can imagine it's the same feeling as when you've been on a boat for a long time and have gotten used to the rocking of the ship, and when you step on land you can still feel the phantom rocking of the boat.
Same with a rollercoaster
Or when you're jumping on a trampoline and then you try to jump on the ground... Oh that disappointment...
@@Domihork *_MY LEGS DON'T WORK ANYMORE_*
Domihork I was just about to comment the exact same thing. Even 2 minutes in a trampoline does that to me.
Or running on a treadmill for a long time...
I feel like I did something similar as a kid, where you find a door frame, and with your arms down next to you, push them against them frame for 30 - 60 seconds. The result you get afterward is that it feels like your arms are 'floating' up from the next minute. Obviously they're not, your arm muscles are just continuing the push from the door in a way. Always fascinated me how quickly the body can just adapt to those odd scenarios.
came to coment that
This was my favorite thing to do as a kid HAHAHAH I’m gonna go do it now
Squeezing two of your fingers on the other hand for thirty seconds and then trying to open your hand again slowly.
i think they were called cloud armz or smt!!
For the specifics of having artificial gravity on spaceflights, the diameter of the cirkel has to be really large. We can fairly well adapt to the rotational forces being constant, but our brain goes haywire when the "gravitational force changes. So if the circle would be too small, just bending trough your knees would drastically change the force you perceive.
A bigger circle also means you wouldn't need to spin it as fast :-D
@@Blackholebirb because the circumference is larger (i gotta explain it to the few that dont understand)
I was thinking about the difference a larger diameter room would make as well. In space you would also end up with 1 G at 90 degrees to the wall not having to mix it in with real gravity on earth. Or just constantly accelerate at 9.8 metres per second per second and there would be no problem.
It would take about a year to reach the speed of light. Then start slowing down at the same rate and stand on the ceiling instead.
Problem solved I reckon 🤠
Also we can't assume that humans can't adapt to a gravity less than earth's and still remain healthy. Maybe 3/4 earth gravity or half would still be ok. All we really know is that zero gravity is a disaster for the human body over time.
@@onastick2411 Zero gravity is a problem over time for humans but mostly because of muscle mass and bone structure. That's why people on the ISS have to work out often, to keep that mass up. I think a healthy person could do it no problem. The only problem lies in the longevity of it. How long can they last? That's a question to be studied.
This is just 6 minutes of Tom having fun in a carnival ride and I’m not complaining.

@@operatorchakkoty4257 Ver-rr-y upztanding work, da!
My favorite videos are the ones where Tom ends up giggling manically with sheer delight at how WEIRD something is
Reminds me of a ride at an amusement park I like! It spins really fast and centrifuges you to the walls of the ride, you can flip yourself upside down if you have enough room to, it’s so fun! And when he mentioned “I swear the room is leaning” at the end of the video, I completely related, I remember that ride feeling like it was tilting, probably just because of the weird gravity going on 😂🤌
Exactly. I went on the same thing. It welt like I was looking upwards but we were really just swimming.
It's called something 3000
Ours was called the Gravitron. I fondly remember one guy who would stand on the wall and even walk towards the centre. Guy who ran it kept a sign with him, "ride has 2 speeds, fast and faster". Good times!
@@dabbydabbydoo Dreamworld? Dreamworld in Australia used to have the Gravatron ride, though little often called it the Vomitron.
I liked it when I was young, it's a pity it's not around. If it were though, current Australian safety bs wouldn't allow you to move around like you could back then 😒
"Gravitron" at fairs and carnivals... same thing.
scientists: so we need 50K to create an anti gravity room
university: granted
scientists: *buys a gravitron carnival ride*
I was curious how far down in the comments the Gravitron would be mentioned.
@@SeanMohundro same
We need this. FOR SCIENCE!
Good luck finding a decent Gravitron for 50k. You might find one that's been beat to hell and needs a new main bearing if you are lucky. Decent used ones are in the 80k+ range.
It was called the Exodus in my state fair. Because...uh, bible country.
I waited for them to start walking on the walls.
But the downward gravity is still there and much larger than the centrifugal force
They'd have to pull quite a few G's before that happened.
Yea they would need to build one of these in low earth orbit for that to work sadly but who knows maybe one day
I was a little sad that didn’t happen
@@ThatGuyNikolas Nah, with 1g, the wall would effectively be at 45° so you could stand on it (at an angle). This setup is too small for lots of more interesting tests though.
This reminded me of something that happened years ago in high school Phys Ed. We were doing exercises with a large medicine ball and of course one of the groups of guys was acting silly and tossing it back and forth as far as they could and trying to get it into the basketball hoop. Lots of fun, but I guess their arm muscles adapted to the extra weight of the ball so that later in the change room, one of the boys went to pick up his water bottle and tossed it over his head by accident!
I went on something like this at a science museum near me. You stepped into a big, round room and stood against the wall (which was carpeted), and it spun up, and then started tilting, but the force kept you against the wall. I thought it was a lot of fun, but my sister HATED it. It freaked her out. :D
I don't know why, but my favourite part is where Tom is describing the tilting movement he's feeling and it's just a sudden panicked *"NO NO DON'T MOVE NO DON'T MOVE NO DON'T MOVE NO"*
Tom's hands suddenly explode from moving, everyone but him are already used to this at that point and are just disappointed while Tom freaks out.
🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮
😆
Same
@kuroryuu010 oh no... The person that stood in front of the projectile vomiter would get saved by the Coriolis force
666th like.
"Thank you so much" walks towards him spinning in circles
I feel tricked
You can do something similar at home by standing in a doorway and trying to push your arms outwards into the doorframe as hard as you can for 60 seconds while keeping them straight (don't bend your arms at all). When you step out if you just let your arms hang free they will raise themselves up automatically for a moment. Your body adapted and is still feeling the effects before returning to normal.
I dont quite understand the similarity, but I remember this cool trick. I did it with someone holding my arm as I try to move it up
@ The similarity isn't to the experiment as a wall but specifically to the bit after the experiment where Tom instinctively moved his hands to the side instead of forward
It doesn't works for me😅
@@cgkstudios4385 it doesn't work for me either
@@cgkstudios4385then you aren't doing it right. It works for EVERYONE
Watching tom struggle to re adapt at the end reminded me of the week I spent sailing of the coast of Scotland after a couple of days on a small 35ft yacht trying to walk on land again was a very strange experience.
Imagine spinning it fast enough that when you throw the ball, you can catch it yourself. From an outside observer, you threw it in a straight line and got to the other side to catch it but to you, you threw it and it curved back to you.
skuzlebut82 from an outside perspective it wouldn’t go in a straight line. From a fixed outside perspective the ball would have a velocity tangent to the path of rotation that the thrower is on.
@@kcwidman When the ball is released, it travels in a straight line from an outside observer. When the ball is released, it travels at a tangent based on the forward speed and the lateral speed at the time of release. If it were to continue curving, it would have to have a continuous force pushing it sideways as it traveled after being released.
@@skuzlebut82 the air is also moving, so it probably will have some effect.
skuzlebut82 your idea would only work if the room is vacuum, so that's not how this particular room works.
@@pheelbanana1646 Vacuum doesn't affect projectile trajectory. Air is only a source of "frictional" force that barely drags the ball. Air and the ball collide, but the momentum is barely affect since the mass of air is so small.
Adaptation applies to sailors too. A sailor gets use to the movement of the ships deck under foot. When they get back on land it feels like the ground is moving for awhile. This happened to me while in the Navy.
I get that after being in public transport after a few hours
Trampolines do this if you bounce for a while on them, solid ground feels strange lmao
@@ravyntaylor6982 after running on a treadmill, it feels so weird walking once youre off, like walking on clouds its so hard to explain
i mean that happens when you ride a bike for a short while already
Oh, I had that in 7th grade when I had a class trip in Kiel (north of Germany). We were on a small ship for an hour in the turbulent weather. The water became wavy and everyone else was nauseous, but I felt great. xD Anyway, when we were back on land, it was really weird to walk. :D
That looked like a whole lot of fun. Amazing as to what the human body and mind can adapt to.
Growing up as a kid. Every summer at my local town fair I would test these same theories on the gravity generator that they had. Back in my day, the walls had sliding seats built in them that could take your fingers off. A small price to pay for science!

They have this as a ride in theme parks usually named “Gravitron”
Exactly
Yes I love that one
I rode it 15 times in a row one year. It was fun because all the kids would try to turn upside down while the ride was moving but it spun so fast even lifting your arm was like a 20lb task. Oddly enough I get sea sick and car sick but not gravitron sick.
@@LC-sc3en
Right!? I get that too! Whenever I go to the amusement park in my hometown I would always go on the two gravity rides (one of them goes almost vertical) and attempt to move (within safety parameters of course) parts of myself like my arms and legs and head even looking left and right. I would rarely get sick from them yet being on a boat or even an elevator would leave me feeling woozy.
Write I had the same reaction 👍🏽🥸
Hey I went on this ride last time i was at the fair.
Remember kids, the only difference between doing science and screwing around is writing it down.
I remember this as the best ride at the theme park. Only we spun so much faster. Best ever! And so true! :-)
@@MilanRegec I remember them aswell. You could lift your feet up and basically be stuck to the wall
Oh Gravitron, how I miss thee.
they still have it at a yearly carnival that comes to my town, also it got banned for a period as people kept climbing to the middle and getting flung into the walls and breaking arms etc.
Adam Savage line, nice
A true testament to how quickly our bodies and minds adapt to our environments to ensure survival

I guess they wanted him to wait for the room to be completely still so Tom could experience the full effect of having to readapt, instead of noticing a partial effect part way through slowing down and ruining the surprise.
It's weird they were serious about that but I wonder how many people turned their head when the tenis ball shot off to the right
Anonlove they’d just get dizzy and throw up. And hopefully not miss their vomit bag.
Damn I remember going to a trampoline park a couple years ago, and I was jumping on the trampolines for hours upon end, when I left the park the rest of my day I felt like I was stuck to the ground
I once got to swim with a bit of scuba gear, and for a few hours afterwards I could feel the weight of the gear even when I had long since taken it off
@@JetFalcon710 I feel that same kind of effect after running on an elliptical for a while. Even when my feet are flat on the ground it feels like I’m still running to a degree
I'm not sure if this is an example, but when I used to take ice-skating lessons (or rollerblade), afterwards, my feetsies still felt like they were being confined to a squeezy space even though I was in my socks
@@KrillChild That's a valid example
@@JetFalcon710 Thank you.
Tom's enjoyment of the literal mind-bogglingness of this phenomena makes the video worth watching!
This would bring 'sea legs' to a whole new level. Space legs...
I have never seen someone so utterly entranced and overjoyed at something as Tom was in this rotating room! 😂
Would it not bi different if you threw something in the direction it rotates, 90 degrees to it or in the opposite direction? Like if you threw it in the opposite direction with the same speed as rotation it should mor or less just stay in place until air friction getts it moving :P while in the direction of rotation, the added speed would make it fall much faster towards the floor since its to the outside, similar if you go, with or against the rotation ;)
Tbh anyone would. Its just such an interesting and unusual experience most humans have not undergone before.
This looks straight out of a Physics text-book...
_Tom is standing in a rotating room........._
_.........calculate where the projectile lands_
Jetlite assume Tom is a uniform spherical metallic ball
@@ToriKo_ Tom is a metallic torture instrument
@@ToriKo_ Humans are generally simulated as a 2 meter tall by 0.5 meter diameter cylinder. But that could just be in thermodynamics.
that seems demanding to calculate.
Tu be fair, what doesn't ? ;)
I felt like this when I went to a fair with the spinning thing, it rotated sideways, still spinning, but it felt as if down was the way we were tilted. Felt like we didn't move, but if you look up, some people would throw up, as it just made your body freak out bc of weirdness. Luckily, the spinning keeps your body from vomiting until the end.
bro i was wondering if anybody was gonna mention that fair ride. It felt like the whole thing was falling sideways but it was just the gravity shift. It was cool, i was able to stand up as it was rotating, the gravity felt stronger though, it was hard to stand up.
@@John-X that's spaceship 2000. At least if the walls slid up.
It was called "the gravitron" in my area
Wow, that looks awesome and very strange indeed. But I guess it must be like when you're going on a "UFO" at an amusement park.

Both scientists: don't do that!
Don't get it
What was the specific reason that they told him not to move his arms/hands at this moment? They never explained what the reason was, as far as I can tell
@@hypnotoad28 Probably minimizing any danger to Tom, as well as (maybe) experimental integrity. They'll have a list of procedures to start/stop this experiment and they didn't want anything unplanned happening in that room during that time. My best guess, at least
@@albpoolshark nope. it's because this is a youtube video. so they wanted him to experience him lifting his arms as instructed so we could see the reaction best.
@@tmass1More likely a combination of those two things. Additionally, they talked a lot about how sick people could get, so they likely wanted to avoid any possible barfing too. Just a whole slew of reasons, really.
Tom…in the midst of this experience your eyes are as bright as a child on Christmas morning.
it's amazing how the human body can quickly adapt to different enviroments
There is a carnival ride similar to this called the Gravitron. It is sometimes called the Starship 2000. The ride operator sits in a chair in the center of the room. The riders lean slightly outward on nearly-vertical beds. It is very cool to experience this effect when on that ride and try to do things like sit vertically on the outer wall, reach your arms out toward the center of the room against a lot of artificial gravity, feel yourself be slowly pressed against the outer wall which slowly becomes the “new floor,” etc.
The Gravitron and I do not get along. The zipper and spinning tea cups also don't like me, I think they're ganging up and it's not fair!
OMG that was my favourite ride, I went on it 10 times maybe more in one day. By the third I was rotating upside down and doing all sorts of weird dance moves while trying to stand
I thought of the Gravitron as well. I've only gone on that ride once and felt quite sick due to whatever force I felt. Made the mistake of having a ponytail behind my back so the entire time I felt like my head was being dragged downwards due to my ponytail being stuck behind me. I wanted to try moving but just couldn't get far for some reason.
YES! The Starship 2000. I remember one of the carnival workers used to walk around in it while it was going. I did not enjoy those wall pads slamming every time they slid when the force changed.
At Great America in Gurnee they used to have the Cajun Cliffhanger back in the day. Same concept except it was open top, looked like a giant old whiskey barrel, no operator inside with you, and you just stood with your back against the wall as they started spinning. Once you were up to speed, the floor dropped out and you were stuck to the wall. It was one of my favorites.
When u realise those spinning UFOs in cartoons could be spinning to simulate gravity
Genius.
the aliens land and then step out of the ufo at a 90 degree angle to make contact
*M I N D B L O W N*
@@tracewyrm *alien steps off ship, immediately faceplants*
I believe there's some references at experiments where the spin is actually used either to power the "saucer" or to counter gravity from Earth and have the whole thing flying.
The tennis ball curving made me think of how the air coming out of the dashboard vents in a car doesn't keep coming out straight when you turn the vehicle.
An interesting thing to test for long term use would be to expose people to the room but have the room rotate opposite directions on different visits to prevent over acclimation to one direction of force. Also assuming in space it would be much less difficult to manage because you wouldn't have to perceive the gravity well that you were currently in, and could walk on the "wall" as if it were a floor.
4:24 That's the best explanation of the coriolis effect I've seen. That graphic helps so much.
I find it very confusing to be honest. Because in the end it's just a matter of referential.

The 2 things that make humans exceptional: An absolutely bonkers aerobic respiration and heat dispersal system, and our neuroplasticity which is demonstrated here. The human brain can adapt in so many different ways, to so many different scenarios. Found myself smiling the whole time I was watching the experience for you.
There is a carnival ride some call it the gravatron, it's a great way to experience this as a civilian although the ride moves much faster than this test lab
"...and use centrifugal force."
_Immediately checks comments for those most affected by overzealous highschool teachers_
Newton's third law: F = -F. If there is a force acting on an object, then there is an equal and opposite force pushing back on the force carrier due to inertia.
Hence if centripetal force from the room's wall/floor is pushing you in towards the centre of the room, your mass is exerting an equal and opposite force on the wall/floor away from the centre.
Centrifugal force isn't what makes the ball "curve" once it leaves Tom's hand, that's true, but it is what keeps him standing at a weird angle, what keeps you pinned to the wall in a Gravitron ride, what keeps the water in the bucket when you do the over-arm spin thing that science teachers love.
xkcd readers unite!
At the specified geolocation to be announced
@@ObjectsInMotion If you're not telling me where it is could you atleast send me the momentum?
1FatLittleMonkey well no because as you just said, the equal and opposite force is what YOU exert ON the wall. That is solely a reaction force and not a centrifugal force. So what keeps you pinned to a graviton is your inertia, because at any instant your velocity is tangential to the circle but then the curved path ‘blocks’ your movement which then alters your direction slightly, and this happens infinitely many times at each infinitesimally small angle. There is no outwards force directed ON the person,. It is the same reason why planets can orbit - velocity would take them tangentially away from the orbit, inwards force of gravity alters their direction. No outwards force on the planet

Seeing Tom having this much fun makes me feel like I’m living vicariously through him. His happiness and excitement are almost contagious
i was in the navy, after every mission on sea ( 2 weeks average) was impossible to walk straight on the sidewalk. I remember walking with friends side to side and we were always hitting our shoulders. At the beginning i thought they did it on purpose, till I did it myself to a friend and then we all realized we adapted to the sea.
The exact same thing happened to me after I came back from a cruise. I remember walking on a trail with some friends and I’d always trip over something or sway side to side
It's also why the navy are seen as drunks. Well, they are, but this doesn't help!
I feel like we will see some interesting muscle growth on people adapted to a rotating room/artificial gravity. To move within something applying a sideways force is to apply more opposite sideways force in order to maintain a straight movement direction
That...
That's a big washing macine...
Bruh it's clearly a rock tumbler... Just with squishy, human shaped rocks.
It's a bit rudimentary but you can simulate the phenomena he's experiencing with his arms all on your own with no special equipment. Simply put one arm straight down against your side, and try to raise that arm up, while using your other hand to hold the arm in place while you push up. Then release your arm and stop trying to push up, and watch as your arm starts to go up even though you're not pushing anymore. Our brains and muscles do lots of little adjustments without us being conscious of it.
another method of this is leaning your weight on the back of your wrist against a doorway/wall for ~30 seconds and then relaxing. the same phenomena occurs where your arm will raise up on its own
I've done a similar thing where you stand in a doorway and press your arms outwards against the frame.
Try it and see what happens. Give it at least a solid minute while applying pressure to the doorframe. Palms facing you.

The amount of force holding me to the wall was so great that I could only manage unsticking my neck. It would be fun to spend more time in one of those rotating rooms.

I'm confused as to the point of this lab. If you were going to do this in space, there'd be no gravity to compete with, and your acceleration would be in a direction entirely normal to the "wall" - so astronauts could just walk on the wall (outer surface of the ring) and treat that as the floor. If done right, your body wouldn't see any difference compared to earth gravity, no?

I love all the ways our brains adapt to "whatever we're doing." Like flipping over your tongue and touching the side, it still feels like the same side. Our brains just... do that
I like holding a small mirror in front of me, flat.....so my brain is confused and thinks I'm walking on the ceiling!
The way you set it up so it is less of an issue in adapting/readapting, is you make the outer wall the floor, then your frame of reference is still skewed, but it is more that gravity becomes weird the higher or lower you are, not that it is a sideways force. Sci-Fi figured that out 120 years ago.
I just watched 6 minutes of Tom having fun and it does bring a smile on my face
I'm about to teach circular motion to my high school students, and this video is gonna be so helpful! Great timing Tom ✌️
Wow, in your school, teachers are allowed to use TH-cam videos to teach?
I wish I had a teacher like you
We are already spinning on Earth at 1000 miles an hour ~1600 km/hr (for modern better measuring).
Then you need to allocate the 1000 km/hr the Earth is moving around our particular Star (the Sun).
But then our Milky Way galaxy is spinning at around 2100 km/hr. Although its also traveling at 2.1 million km/hr through space.
But since the universe is expanding at 70 kilometers per second, then everything is kinda in perspective to everything else.
Einstein's law of motion actually showed us that if you were in a car doing 100, you could throw a ball up and down inside the car and wouldn't move at 100 km/h in the cabin itself for the inside observers point of view. But for observers outside the cabin, the ball definitely made a huge symmetric curve at 100 km/h! Which is really strange the more you think about it, because if you throw the ball out the window it immediately travels really fast at great distance!
@@kimsland999 doesn't matter, everything is relative... to us everything else seems to move but we stay still. Nothing is right or wrong apart from the rotation bit which obviously only you can be rotating and not the entire universe that's rotating.
Also dont forget centrifugal force depends on the RPM not the actual speed.
@@iCore7Gaming Maybe children enjoy spinning in circles because they are trying to be in line with the entirety of reality, and that when they stop doing this they have inadvertently adjusted to circular movement, and thus not living in reality any more? We need more child scientists to inform us what's really happening.
Son why are you spinning?
To compensate the opposing momentum of gravity in space-time across our known universe as I have not yet adjusted to to your world of circular nonsense.
Seems reasonable :)
I always knew how it worked but couldn't visualize it quite like that. This was awesome
Here in Brazil we have something like this, at the amusement park, and it is call SAMBA, it's a rotational disc, you can sit down, or stand up, or if you are bold, walk right in the middle and sit.
That was nice video. Definitely a few things to think about.
Bruh what’s your channel jeez
@@prwdmex we hit the jackpot boys
The Expanse books really hammered the whole idea of artificial gravity home for me. Really cool how they integrate those ideas into the storytelling - spinning up asteroids with space stations built into them to achieve this artificial gravity effect, less pronounced as you move further towards the center of the station, or the thrust "gravity" created by propulsion in their ships.
Nothing makes scientific concepts easier to understand and remember than when they are written into engaging sci-fi narratives.
Exactly! The main difference is that the ships in The Expanse use constant horizontal acceleration (which requires no adaptation, since it mimics Earth's gravity), and the space stations/asteroids in The Expanse are large enough to minimize the Coriolis effect. Until we achieve either of those, we have to figure out how to deal with much smaller rotating systems, where the Coriolis effect is very pronounced.
@@kentslocum For people who have not read the Expanse books, on space stations that rotate the richer and more well off live near the outside, while the poor live closer to the axis of spin where the Coriolis effect is at it's strongest.
@@Paulysolo True. Though they take medication to try to counteract this.
I love these sorts of videos cause typically it feels like channels like these know everything but when someone is teaching tom something i feel like i'm him. :)
it makes morse sense to explain the difference in perspective from the balls point of view, and then what the human observers. Combined with the gradient map of relative speed, it would be easier to understand for someone struggling to grasp why the coriolis effect appears to have changed the path of the ball, when in fact it has not.

Isaac Beitzel finaly I was looking for a comment like this😂
Outstanding move
It probably works the same, if I ever go on one of those rides I would want to try this
10 RPM is, to use a technical term, insane.
10 RPM ... it's fast ...for a full room tho that's INSANE
@@amineabdz Isn't that only 10 Rotations per minute..? Thats one rotation every 10 seconds, don't most carnival rides go more than that?
@@lurac5710 TIL a minute has 100 seconds
@@JesusJuenger Naturally
That's o
There was a room similar to this at a carnival I went to as a kid. One of the most popular things there.
What a fascinating video. I knew of artificial gravity simulation via centrifugal force but never considered just how much it would affect a human in that being closer or farther away from the center like that would have such severe effects… thanks for sharing !
I guess this is why aliens make their flying saucers round.
AND rotating
science fiction usually has _some_ elements of truth to it.
Tom Scott literally went "Woah?!, WUT!?!" at 3:08
Idk why but this is hilarious to me
In the 80's this was revolutionary, but in the 90s I was doing this at every town fair.
“We started designing it in the 80’s”?!? This has been my favorite carnival ride since at least then! Has everyone not been on the ‘Gravitron’?
This is probably the most fun I've ever seen Tom have. Made for a really really enjoyable video as well, while completely breaking my brain with that ball.
If the room rotates fast enough, the ball will return to the thrower. :D
@@sleeptyper Really, you just have to have enough headroom to make it stay in the air for half a rotation - less if you don't have to throw directly towards the center.
@ Problem with just tossing the ball upwards is conservation of energy - the ball has already some rotational momentum that you have to cancel with your throw towards the center.
@@sleeptyper Well, once you let go of the ball it flies straight in the horizontal plane. If the momentum carries the ball away from the center, you didn't throw it towards the center but off to the side from the start. It is only because you are inside the rotating frame that it looks and feels weird when you do stuff. 😉
The ball also demonstrates the Coriolis effect. It basically makes wind going in a straight line seem to curve.
This video is 10/10 the most wholesomely endearing thing I've seen all day. You can feel how genuine the excitement is in everyone in the room and that's just dandy if I do say so myself
I know very few people who can make a really interesting 6min+ vid about invisible forces affecting their inner experience of 'normal' and have it work. WD Tom!
Imagine all the adjustments and accommodations your body is subconsciously making in everything you do whilst going about your daily lives that are specific adaptations.

Was literally scouring the comments thinking, "How is nobody commenting on this?" 😂
If say you send a ship to Mars you won't have to worry about two forces like you did in that lab. You'd be standing on the outside walls. The only time you'd have to worry about the Coriolis effect is if you moved toward the center of the the ship. Ideally you'd want to to have the outside ring as big as is practical. I could see two pods at either end of a frame, one for storage and one for habitation.
Doesn't that spinning even outside of apparent gravity still produce a coriolis force and wasn't that proven to be problematic just because of the average human height? Like different force on your upper body vs. your lower body.
@@Washeek the bigger the circle, the smaller the difference. This room is way to small.
@@catocall7323 Sure, I understand that, but there was a nice video series that showed that the size where this would not be an issue is currently quite impractical.
That 360 cam up top ,as soon as the room starts moving the floor became spherical 🤣🤣🤣
This has to be the most epic game of catch ever played on Earth
In the US at most every fair there is a "Gravitron" ride in the shape like a flying saucer that you climb in and put your back to the wall. The Gravatron ride is much like this, however it goes much faster.
And you have to watch out for the sticky spots...
The ones in the mid-west here used to spin you fast enough to stick you to the wall, and then the floor would drop by about a foot and leave you stuck there with your feet off the ground.
we call it the puke-atron
Yup, much higher than normal "gravity"
@@The_Original_Brad_Miller Six Flags Great America has or had one, its been over 25 years since I been there. The Ride Operator would get on the intercom to tell people to stop trying to climb the wall. Good Times back then!

I’m so happy you explained this because it such an important concept to grasp
There is no force pushing the ball to the side
Just like on a bend in a car there is no force pushing you to the edge of the door
You or the ball are moving along their straight line path but everything else around you is moving at a different speed at a different direction
You aren’t being pushed into the car when you go round a bend
You are moving in a certain direction and the car is almost turning into you and crossing your path.
Anyway, this is tricky because there are 2 forces that interact. But in space will be only one.
@@ehombane no, you'd have coreolis force even in space. This happens in earth as well. Wind/water streams automatically "rotate" when the trying to go north/south
@@ehombane He needs to send the ball forward and left. Both directions are orthogonal to the planet's gravity and not affected by it. So this would work in space or any planet/satellite.
In space, it just wouldn't go "down", "down" as in how the room *looks* in the video. Obviously without feeling gravity and with artificial "gravity" the frame of reference for "down" will also change in space.
@@iwatchwithnoads7480 Let talk about vectors not directions to be more precise. So on earth we have a single vector called g. We drop the ball and the ball is following the vector, will go down. Now, in the room we have two vectors, g, and centrifugal force. therse two vector combines and give the down for the room which is a circle around the edges of the room. On earth if I throw a ball to you also will be two vectors, one the force I throw the ball and the g. And this will give a curve. I know it and this is why I throw up in order to aim at you. Now, in the room are the two forces g end centrigal, combined gives let say Gr the gravitation of the room. And obviously will influence the ball even my throw is orthogonal on them, but I know it and I compensate throwing up. But there is also the other vector, the room rotation. So in the second needed to the ball to reach the other wall, the wall, I mean you, will move few degrees, So this is why I need to aim ahead, of rotation.
But in space we have no down, the forces cancel each other, and so there is imponderability. And sure if the object we sit on or in it is rotating, (fast enough) we need to compensate the rotation to cancel the coriolis effect.
But if the object is not rotating around its own axis there will be no coriolis effect. This is what I meant.
@@ehombane The curve caused by g is the "downward" curve. It is orthogonal to "horizontal" (XY) plane, and thus does not cause or interfere with curves observed in XY plane. So that profile doesn't change in space at all.
When not in contact with anything that's rotating, there is no centripetal force being exerted on the ball. In fact, it has no force on it relative to the room after it leaves hand, ignoring air resistance.
I should clarify at this point that "coriolis force" is an idiomatic force, not a real one.
Humans really are quite incredible. Our versatility and adaptability is just... Wow.
There's actually an attraction in a theme park I've been to that looks exactly like this, the walls had mats for when the it rotated very quickly, the mats would just slide up the wall(the wall is curved so it can do that) like magic. I will say it's very very trippy and a fun experience.
That ride was always my favourite! It was always funny trying to get back out of it, feels like you've got the spins while sober. It would not be fun trying to adjust to that feeling if you had experienced it for even a week straight.
The round up was similar to the gravitron (which is the one youre speaking of), but it had a hinge-style lift to it, so that the spinning circle would become upright like a hamster wheel, but a little less upright than that. Ive worked for midways. And although guests werent allowed to do this, those of us who worked there would often ride this ride, and when the ride would get going fast enough, we would slowly move so that we would be standing on the wall part, where you would normally have your back up against. So that we would be standing almost completely upside down, while going around the top part of the hamster wheel.
If that makes sense?
Gravitron / rotor rides
I think thats their name
Rotor is the more clyndrical one and has the floor lower for riders to be suspended above it whereas gravitron has a somewhat inclined wall where you slide upwards as you get pushed outwards by the inertia.
@@MissHellKitten must've been fun xD it must've been like a stand up enterprise ride
some dude threw on one of those and the throw up was literally floating in the air like alien blood just slapping each person one at a time. ppl were trying to move away but the force of gravity kept them stuck it was like a horror film after words.
The part that really drove home the point of adaptation for me is when the room stopped spinning and your arms went sideways when you tried to bring them up straight
A good way to experience something similar.
Stand in a door frame with your arms at your sides.
Now raise your arms sideways until you're touching the door frame and apply a small amount of pressure for about 30 seconds.
Now step out of the doorframe and just let your arms hang by your side.
