- A popular "magic" trick can also be a great learning tool for students to investigate. Starting with the original materials and then going larger plus watching it in slow motion makes the science behind the behavior easier to follow. This video offers a basic explanation of the concepts involved, an in-depth explanation of the physics of the ring and chain demonstration can be found in an article published in The Physics Teacher. online at: aapt.scitation.org/doi/full/1...
The sound of the large ring and chain is incredibly satisfying.
Well, there is a catch to it (nothing is free)
Especially in slow-mo
Wasn't expecting to see you here man :D, love your videos so much
Gay, you are here just to copy something from Bruce. You should be cancelled.
I love your videos. I’m thankful for your work outside of work. Need more guys like you teaching the future generation.
the science teacher we all wish we had
i had him and he was creepy af to girls.
ProxEe i don’t wanna trust you
Where's the science?
This gives Veritasium’s video a run for its money.
And I don’t care how much I understand the principle, each and every time I see it, is magical. It tickles the brain so easily.
I have watched all your videos. It always goes like this:
1. That's so simple, I know exactly what will happen.
2. I don't even know what just happened...
3. This is awesome! I need to try it!
Spectacular as always Bruce!
Thank you for continuing to make videos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This channel is a substantial contribution to my science hobby and education! Thank you!
Thank you Bruce you are always a source of inspiration.
You are amazing
Thanks for changing and showing the different variables! 😁
We love you bruce!
Brilliant, I finally understand. Thanks!
That’s so cool!
This is the least dislike ratio I have ever seen on TH-cam. Great video from a great teacher
Nice work!
You are such an awesome teacher 👍
Next it gets upscaled and needs..... a crane!
now that would be fun, and as long as I have the use of a crane, there are a few other things I'd like to try
@@YeanyScience I would chip in for a crane rental in a heartbeat, you're an inspiration to us all!
Great video as usual. Thanks for sharing
Very interesting. I like your way of explaining science
Seus vídeos são muito bons!
good job John
Awesome 👍😊😁
Bruce, you are a goat. this is some really cool stuff, I really gotta commend you for being able to keep this stuff up and keeping it enjoyable.
I still enjoy it myself and having a channel is more incentive to try some ideas that I thought others might like to see
y = ax² + bx + c where parameters are “a” as astuteness, “b” as brilliance, “c” as creativity, where “x” is the unknown and finally where "y" means Yeany, of course! Thank you Bruce for all your wonderful videos!
LOL, thanks for the equation, I'll have to print that one out
I am flattered. Thank you! I'm French (68 yo) and live in Toulouse (South of France). :-))
LOL Mr. Yeany, you never fail to impress me
RATED: 💡💡💡💡💡
9 out of 10 Wizards liked this video
I wonder what the 10th wizard didn't like
GR8T QUESTION 🥇
I asked and s/he said it ended to soon. I also can agree. The word BINGE was peppered through our terse conversation. We [will stay] tuned 😁
❤🔎💡🔭📚🗿
Thank 👉 You
Brilliant! :-)
Wow, so glad you weren't pulled over the edge by the force at the end, that would have been terrible! Great magic/science trick for sure. Look forward to showing it to my students.
If I had held it a bit more rigid that might be a problem. The tube is filled with wet sand so it does have some weight to it, even so, I was surprised with the amount of force needed to stop it as it reached the bottom of the loop. You can see that I give it some slack as it stops, otherwise I snapped the chain a few times.
1:20
I have that same spool of doorbell wire. It's great for the little hobby electronics projects I do from time to time.
Very nice
It was amusing you included the footage where the chain failed at the end of the video!
This is your daily dose of Recommendation
Upscaled ring chain magic
Very catchy chain recommendation!
@@commonsense4993 yess
WOW
Oh no! Why did you have mixed results that last set-up?
Also, can this trick be used to undo the loop?
wow
4:53 lowkey thought he was gonna be pulled over the ledge 👀
V cool trick tho
Knot cool
Hi Bruce I just saw a video online of a guy who boils a bit of water in a large glass bottle then caps the top of the bottle. Within a couple of seconds the water stopped boiling but then he slowly started pouring ice water over the bottle and the water inside started to boil again. Was wondering if you have ever made a video showing how water boils at different air pressures? Thanks love your channel
Hi BigBall, that's a pretty good experiment, I hope to make a video on showing reduction of pressure done a different method.
Bruce Yeany awesome, I think it is fantastic keeping students and the general public interested in science as well as helping them understand how things around us work on a daily basis. Keep doing what you love and we will be there absorbing every bit of it.
I wonder, just as another variation, if a triangle might work if biased properly?
good idea, I'll give it a try
Hi Bruce, Have you started making new videos or are you sharing old material? It looks like you are back at your old school. Cheers?
Hi Morten, recently posted videos have been a combination of old and new while this video was shot entirely last week, partly in my garage and for the balcony section at a local college. On occasion, I am back at my old school presenting or substituting when they need it so I may get some video from that, you'll see more shots at my garage in the future plus at the local college if needed.
Next time we're going to see the teacher jumping off the top of a building, strapped to a ring sliding around a chain, to demostrate how you can depend on the law of physics.
Next time we're going to see the teacher jumping off a hangman's gallows, hands tied, strapped to a Hangman's noose while executing a single Forward summersault to undo the noose.. the law of physics awaits the challenging teacher..
I Got my popcorn on standby.. whaddya say teacher??
wuttttttt, I learned a patry trick in 5 seconds, nice
5:43 sometimes the chain goes through the ring, sometimes the ring goes through the chain
He pushed it at an angle such a way that the rings should swing inside the loop, which will then snag into a knot
My teachers were never this cool
thank you very much.
you save my day.
i've wasted my time to watch some idiots' videos
Where'd you get that ring?😶😳🙊🙈🙉
The small ones are commonly sold in hardware stores. The medium sized one is made out of about 2 feet of garden hose, sand was added then a short piece of wooden dowel was inserted as a plug, finally wrapped with colored electrical tape. The large on is a piece of 6 feet of plastic water line pipe, filled with sand and a piece of wooden dowel inserted as a plug, then the joint wrapped with black electrical tape
I'm both watching this for learning and how to prank my friends
with a little practice, it's a good trick
Well, so far, 2 magicians didn’t like the video.
Bond. Bruce Bond.
Dude can I attach the moon to the earth with a big chain? I mean, hypothetically, what if? or, could we just use a planet as a ring and then what if we put a huge chain around it like this?
The chain, unless made of something insane, would snap under its own weight. If you could teleport it into position, probably somewhere around the L1 Lagrange point.

The chain breaking isn’t that surprising 🤣
3:00 I have to stop you there. Gravity always grabs at the center of gravity, which is for all reasonable intents and purposes equal to the center of mass. Gravity therefore never applies a torque to anything. This is also the basis for the pendulum falacy. Gravity isn't torqueing the ring, you are.
Great video again, another experiment I should really try myself. I only have some nylon string on hand though. I have also made a 3D printed centrifuge puzzle toy. I hope to upload a video about it soon, along with the file to print it.
Can you only take torque about center of mass?
@@replicaacliper In a way yes. For free bodies all rotations are around the center of mass. This is for aircraft, missiles, falling rings etc.
For bodies mounted on shafts, the rotation will be around the shaft. But if the center of mass is not on the axis of rotation, the bearings of the shaft must constantly exert a force to keep the shaft from flying off, and that force changes direction constantly.
I happen to have a video about this on my channel, about static and dynamic imbalance, though what I talk about here is only static imbalance. In the video I discuss it from the wheel's point of view though, so with centrifugal forces.
@Antalz. It's not a free body - he's holding it! And by the edge, not the centre of mass.
@@hermitoldguy6312 Yet the ring ends up rotating around its center of mass, which gravity can not have caused, because gravity can not produce a torque about the center of mass.
@Antalz It doesn't matter how many ways you try to re-write it, it's not a free-body. It's held by one edge. 2:50 IT IS DEMONSTRATED. You're trying to argue against demonstration! Gravity is producing a torque *before* the ring is released.
Oh, and by pointing to 3:00 you conceal that very demonstration at 2:50.
Concealing the demonstration that falsifies your argument is evidence of bad faith.
You're a troll - and not as smart as you think you are.
Didn't veritassium do a video on this phenomenon?
I think his was with a dumbbell attached to the end of a chain, vs just a dumbbell
Actually no I think you're right, he's done both
This trick has been around for years and along with the dumbbell drop, youtube has several examples of it, I thought it would be fun to see if it could be scaled up and it worked better than expected
First
Teachers are the opposite of magicians, one does everything they can to make sure their demonstration communicates the principles which explain it, and the other does everything they can to make sure their demonstration hides the principles which explain it. The way I see it, teachers are just better, because you can get just as much if not more wonderment from seeing how reality actually works than being tricked by your own perception of it
Thanks Jake, I had a saying that I posted on my wall for years with a similar thought. Magic deceives, Science reveals.
