- In this video I put kinetic sand in the vacuum chamber, then I also pour liquid nitrogen on it in order to see if it still acts the same under vacuum chamber and when it is very cold. Kinetic sand works by mixing regular sand with PDMS (polydimethyl siloxane). I was very surprised by the results! I love doing experiments and being surprised because I always learn something new.

Until I saw your hand under the chamber I was like *WTF?*
I thought it was becoming magnetic
idiots.
You 3 are living proof we need more effective birth control methods
Ants in my eyes Johnson both of you are just bullies who sit behind the safety of their laptop/desktop and write hatefull coments like this one😑😑😑
I get it I miss spelled safety
Remember when they called it " moon sand" or 'moon' something
hoodie proxy 🎵Moon sand, moon sand, the sand that molds like dough.🎵
Marikroyals dah dah
hoodie proxy I was just telling my husband this.
Tylar Iosue that was aqua sand.
Nico Niner yess. I had that as a kid. 😂. Also, noice name and profile pic.
As you removed the air from between the sand particles, it became less "fluffy" than when it had air. This is opposite to when the sand just sits for a while, then you pick it up and fluff it up by incorporating more air into it.
+Mike Holland maybe…but if I had a piece of cotton the cotton wouldn't be less fluffy in a vacuum. only if you were vacuum bagging out where the atmosphere was crushing it than what it become less fluffy… That's what I think at least
Cotton balls are much lighter and have thin fibers that help hold it's shape (with or without) a vacuum. The sand relies upon it's density (or gravity) and the air between it's particles to make it flow. You basically showed that when you started the video. You had a tight lump of the sand, and you cut it with a knife. It was less "fluffy" because it had been packed (either by you packing it by hand, or it's own weight). The vacuum chamber simply helped take the fluff out of it. I think maybe the moisture you mentioned may still be a factor, but only in it's fluidity.
Water moisture + silicone-based products dont mix well. I dont believe any hydration in the atmosphere around the sand would affect its fluidity. Merely the temperature and atmospheric pressure.
This is exactly what I was thinking as I watch the vacuum chamber bit. I had the video on mute, so I didn't even hear that he had thought it had to do with pulling water moisture from the mix. I'll leave this link to another video about how air can help sand act more like a liquid to further illustrate your point: th-cam.com/video/My4RA5I0FKs/w-d-xo.html
I agree, I think those little pockets of air helped keep the sand particles apart, under vacuum the particles tend to clump together and playing with it would make it less and less fluid
That was very smart to use magnets to test the sand's properties. I don't know if I would've thought of that myself.
wow, now l want kinetic sand, way cool! loved it!
Momma O trust me, i only used it for the first day. Waste of time and gets boring and old
Yes and if you leave it for a long time, it gets sticky, and it sticks to everything, leaving an oily residue.
Momma O it’s very satisfying
Momma O but you NEED to keep it in an airtight container.
Momma O lol i have the regular sand color one and the pink one in this vid
I really like how he amazes himself when doing experiments while he's making these videos for us. Its just something I thought was prettt cool cause he know what's going on but he doesn't know what will happen at the same time because he does the experiment with us instead of doing it off camera then seeing what happens then doing for us on camera that's why I like this channel alot
i thought that magnetic balls are moving by themselves.
I did start to think that for a moment, since it is sometimes difficult to know what to expect with the vacuum chamber :) I did expect it to solidify slightly so some things can be predicted.
balls moving by themselves? Don't be silly. Tht's like believing in magic. No, what he did was he used telekinesis.
Ha ha same but I saw that he was moving it later
if you put the sand back in the vacuum chamber after you put it in the nitrogen will it go back to normal
And that would be a way to confirm the guess about humidity affecting its viscosity.
damnamas I was thinking that too lol
I think I figured it out! In the vacuum experiment, air would help the kinetic sand flow(not inside the vacuum) like water from a bottle because if you have a water bottle and you take off the cap and turn the bottle upside down the vacuum holds the water in but then air is light in weight and goes up in the hole in the bottle and makes some water come out bit by bit. So now that you put it(the kinetic sand) in a vacuum air makes it flow easy but without the air it doesn't flow like it usaly does because it has a liquid type substance in it. When you were moving it with the magnet in the vacuum only gravity was making it fall(but at a slower rate with out air)

Love the vacuum chamber experiments
"experiments"
Yeah I wasnt correcting him. My intention was to point out how ridiculous it is to call something like that an experiment.

Hi, my six year old is requesting an experiment with play dough. Thanks
Peachumms its not coming

Peachumms seems legit
That's adorable
GuyWithDaHat which is obviously why their parent is the one making requests. You’re annoying. Youve made negative replies to other comments too. Go away. Nobody likes you.
Imagine accidentally creating a black hole in your vacuum chamber , freaking neat XD
Mixey I don't think that would happen because black holes are mainly caused by immense amounts of gravity, theoritically they are holes in time space
Black holes form under extreme gravity. If they formed in a vacuum then they would be popping up all over space, and that would not be good o.o
Black holes are made when a HUGE amount of mass is compressed in a VERY small volume.

Cuz it is a MISS STEAK
TheLegend27 couldve made the joke funnier
Why would you ask for a medium well steak anyway though...
Isn't kinetic sand hydrophobic? I don't think the water vapor matters too much
I think the kinetic sand just needs the air to be so fluffy. With out air there enclosed in the sand there is nothing holding it from the inside. Just my simple thoughts though let me know what you think.
WAIT, what would happen if you put a vacuum in the vacuum chamber?
VACUUMCEPTION
i just watched that
*It becomes one with vacuum.*
Good job 👍 keep up the good work keep uploading love your videos
My theory is that because Kinetic sand is light because of all the air in it, it starts compacting into a harder, stiffer substance that is heavier, thus resulting in a more stubborn form. Although I do not know much about vacuum chambers, I'm pretty sure there is some sort of pressure being pressed on it. Even if it's just a little bit or a lot, it can effect the state of the object. I love to see your enthusiasm and curiosity come out in this little experiment, and I've even subscribed and watched a few other videos of yours :) Good Luck! -a future paleontologist
Veridisaurus The whole point of a vacuum chamber is that it removes the pressure by taking out the air. I would just guess that the air helps it flow, since air is a fluid.
As someone who has a lot of experience with toddlers making messes with kinetic sand, I recommend grabbing a handful of sand and seeing if you can dab the sand off the leather gloves- like using a ball of play-do to pick up little bitty pieces of it. Not sure if it'll work with leather, but it works for carpet and most clothing
Cool
you can pick it up with itself.
This is probably the first video of yours I’ve seen, but have you heard of liquefaction? When normal sand is steadily pumped with air, it behaves like a liquid. Knowing that, I wonder if it is even more stiff in a vacuum, and perhaps that has something to do with it.
The Action Lab Please try an experiment to see what happens when water containing soap/detergent is kept in your vacuum chamber. Will the water form froth by itself or will soap bubbles rise? Also, can a soap bubble survive in a vacuum chamber? What happens when there is no pressure outside the soap bubble?
Nikhil Madhusudan
This experiment would be interesting.
I would love to see the surface tension of those three phases change in vacuum.
Rick Chen Thanks for the appreciation! This channel has performed lot of experiments on vacuum chambers. I checked the list of videos and I found that he has already performed that experiment.
Air is a fluid. When you vacuum out all of the air, you reduce the space between sand particles and make that space more dense.
+Sponserthis sucking air out doesn't reduce the space though. for example when I suck all of the air out of my vacuum chamber the volume in the chamber stays exactly the same. When there is atmospheric pressure around the space that is getting the air sucked out then the volume will reduce. But in this case the space around it was also a vacuum so there would be no volume reduction.
The Action Lab you are correct, my response was poorly worded. Better description would be that some of the air was taken from the silicone compound, making it itself more dense between the sand particles.
Say you put a cup of syrup in the vacuum chamber. Once vacuum is achieved, you would see bubbles coming out of the syrup. It is pulling the air and other less dense materials (that are not mixed in well enough) out of the mixture to the surface. I would also put money on the "bubbled-out syrup" would also have a noticeable increase in drag. Then imagine that with sand mixed in. At a 2% adhesive content, you would more than likely not see a visual change, but you could feel the difference.
just had a thought, place it on a shelf inside the chamber with a bar magnet to see if you an get it to flow off of the shelf too see how much the liquidity has changed. Great video and channel keep it up
That's so

Dude you comment on every video your so annoying
At first i thought the magnet was moving by itself 😂
i was just watching some of your videos putting non Newtonian fluids in the vacuum chamber... and it reminded me of something..... SOURDOUGH BREAD!! the way it bubbles like that.... is there anything you can do with making sourdough starter in the vacuum chamber? does it speed up any reactions or how does it affect the making of sourdough starter? i can send you a link to a sourdough starter recipe if you are interested... who knows, it could lead to some sort of speed bakery.... lol
Sourdough rises because the yeast produces gas bubbles. I’m pretty sure that if you put dough in a vacuum it will just kill the yeast. I’d still like to see him try it though, I could be way off
I can already tell these types of videos are going to result in humanity solving the riddle of the universe...
The magnet is actually helping the vacuum chamber take it into pieces good work.
Atmospheric pressure pushing on the sand seems to be why it moves better with out the vacuum . The pressure from the air seems to help it move
Those two little magnets moving around is so cute 💜
My ears were clogging just listening to this!
6:48 oof
To remove the sand from the leather gloves, use a toothbrush to brush it off, or just a general cleaning brush.
That is cool and ur explanation is great as always
I might suggest furthering the experiment by testing the material with various levels of humidity, using a humidifier and/or a dehumidifier
Great! If it's the moisture you could try putting the sand in a hot place so that it looses moisture also and you can compare the results
1:59
*vacuum starts*
Magnet: AHHHHHH I GOTTA HIDE *runs around panicing*
*goes to the store to return the kenedic sand*
Store clerk: would you like to return that?
Me: this is false advertising IT CAN DRY OUT
Store clerk: did it dry out
Me: no I watched a TH-cam video, put liquid nitrogen on it
Store clerk thinks: I hate my job-_-😂
Store clerk: I also hate your spelling.
my guess on why it is stiffer in a vacuum is because sense there are no more small air pockets every where inside you are actual slightly compressing the sand and increasing its density by shrinking its volume.
Considering how the amount of space between the sand granules would decrease with the lesser amount of air in the environment surrounding it, one can make the assumption that it would condense and become compacted, even if the difference is slight. This would explain the “stiffness” you observed.
Can you please test ice also snow in the vacuum chamber? Does it melt? Could we follow the temperature with termal camera ?
Ferenc Scherman why would it melt? All the vacuum does is suck out air from around it, that wouldn't affect it.
Cody’s lab did the snow thing. It just sublimated.
I meant by the water starts boiling lower temperature at less greater air pressure, that could be affect on frozen stuff too.
the sound of the vacuum pump is satisfying
"it seems a little bit stiffer than normal"
maybe that's because your using a magnet to try and push it around?
Yay almost 1 mil keep the great work up!😇
The most most important thing when you're doing science is to document it
Removing the moisture from air is way difficult than you think. You may have to bake the chamber to actually remove all the moisture.
this is gonna give me a stroke

I have kinetic sand it is fun to play with.I had it for one year
It’s amazing how ppl can get popular just by having fun.
Also, 200th comment, woo
You always block the shot with your arm at the best part on a lot of video's. lol
How much did your vacume chamber cost
Neelsen Bugayong he made it
you can buy one for like 200 with pump included
Neelsen Bugayong it costs 5,000 dollars 💵
+S A (SP) pounds or dollars?😕
Probably less than lays chips
I bought kinetic sand and it says it never dries out. So if I leave it in the play space for a few days it won’t dry right..? Also nice video!😀
I had thought the magnet was moving by itself. ^^'
I learned a lot today. lol
Nice videos thanks.
You put everything in a vacuum chamber I like that tho the results are always cool
"Look how more liquidy it seems" real scientific and descriptive
When you were tearing a piece of with the magnet I thought it was doing that by itself and I was so confused lol
so wait i can make this with just sand and lube?
Danie E 😂 when you put it that way... maybe
You know how everybody has liquid Nitrogene in their backyards. "Hold my beer, gonna get this real quick".
I wonder if the air itself acts as a lubricant between the particles of sand and silicone allowing it to flow better like ball bearings
really good and satisfying video
That looks soo fun with that magnet
When you were using the magnet I was like:
JUST TOUCH IT ALREADY
For a second I thought the magnets were moving on their own 😂
Idk why but I love his voice
Wow did not expect that to happen... Definitely one of the weirdest things I've seen
No, the reason why it's more stiff in the chamber is because the air pockets in the sand get sucked out, making it more dense, furthermore stiffer.
I was genuinely like why is the magnet going crazy
Him: I suggest you guys do stupid little experiments
Me:😆 how you said that!
Omg I didn't see your hand under the chamber and I was really confused and somewhat disturbed (for some reason) with the magnets running around.
It would be stiffer because the air is pushing it together making it tightly compacted and stiff.
Its 3:45am and I'm watching random stuff on TH-cam that's fair enough😂😂😂
*plays with kinetic sand in a vacuum
Can you explode a firecracker in the vacuum? Maybe try those snap pops that when you throw they explode? They make big ones just as loud as a normal firecracker
And good times were had by all!!!!
PS: put it back in the vac for a while to dry it out and then test it's fluidity. (obviously somewhat subjective)
The magnet looks like a little person playing in the sand xD
Pour it from a magnetic cup next time like you do water. You will see how it pours out if its changes or like normal under vacuum
Do you think the Kinetic Sand becoming more firm could possibly have something to do with the increase in pressure in the vacuum chamber? Similar to that of a submarine.
You need an EMERALD play button
Might be that lower pressure means that that oil you were talking about solidifies a bit to make it stiffer
I know I am 4 years late to the party but the air moisture theory can be tested. Just put a jar full of sodium hydroxide in a vacuum chamber with the kinetic sand and seal the chamber (without pumping out the air). Sodium hydroxide is extremely hydrophilic, and given the chance it would suck all the moisture out of the air. So if the seal on the box is good enough then the air inside will become as dry as it gets.
The magnet was a smart idea!
What you should do now is take the kinetic sand that had the liquid nitrogen poured on it put it into the vacuum chamber and see if that makes it more like its original state.
Love your vids!
There was many channels who did the thing were you put sand in a tub and in the bottom, you poke holes for air to blow thru. and that caused the sand to act like a liquid. like if u were trapped in the sand, you blew air thru the holes the sand would be like water for you to get out.
Surface tension of the pdmf changes when not in contact with the air.
2:29 OMG! O.O I was imagining how would be if that chamber implodes, when it almost fell of. I literally lift my hands trying to catch it xD
When you thought your grades was straight but when you check them just to see it crumble right in your hands
With your liquid nitrogen experiment you made me hungry
3:47. I think it flows because the air inside it Makes it soft. It’s like getting cotton candy and Sucking all the air out so then It becalmed stiff
How to prepare kinetic sand..perfect solution
Was it only me who got a kenetic sand advert before this???
Could the cohesion between the particles be higher due to lack of air/ water in between particles? And hence behave more like a solid
Well it's easy to clean when you're a normal person and not poor liquid nitrogen onto it! Tbh though this whole video was really satisfying
You should have put the kinetic sand back in the vacuum chamber after the liquid nitrogen to see if you could pull water out of it and get it back to its original state.
