Pendulum Wave Toy

__________________________________________________________________
You can see bigger versions of this scientific demonstration in museums and science departments. But we think this might be the first time it has been produced as an affordable table-top demonstration.
Fifteen ball bearings hang from a frame, suspended on fine threads. However this is not a version of the famous Newton's Cradle. Here the ball bearings are not touching, and in addition, each ball bearing has a different length of thread supporting it. The time a pendulum takes to move to and fro is dependent on the length of the pendulum. And here we have fifteen pendulums, all of different lengths!
Using the supplied wooden bar, move all the ball bearings to one side, and then move the bar out of the way. All the ball bearings start to swing from side to side. Initially they all (nearly) move together, but very quickly, other patterns start to appear....

+Ben Abbott Thanks .. I guess it would work like the Newton's cradle, if the marbles didn't have gaps between them .. XD Hypothetically speaking ..

[@zayncelio6823]

+Freya Okami Not similarly. The pendulum wave has strings that range in lengths. The ball on the shorter string swings faster while the ball on the longest string swings slower. The newtons cradle will just swing back and forth without any patterns forming except for a straight, swinging line

what if you used it in a vacuum with magnetics on each end? Would it swing forever and have I just created a perpetuum mobile? :D

[@yesitsvish]

TerrorJesus no its still subject to gravity and entropy.

[@Windy2468]

yesitsvish wait, entropy aside, why would gravity eventually stop it? kinetic energy will just convert into potential energy and then back and forth

[@yesitsvish]

but its moving parts are still subject to friction. also because Newton perpetual motion is impossible.

[@RFC3514]

TerrorJesus What are "magnetics", and why would you need them? If you managed to eliminate friction _completely_, yes, it would swing forever. But you can't. Even in a vacuum, there's friction between the toy's parts (although eliminating air friction _would_ make it swing for a lot longer).

I think the visual would be even better if rotated 180 degrees with the camera looking under the balls. No strings in the way.

[@funky3ddy]

Under the glass table?

[@jpopelish]

funky3ddy The black plastic base makes that pointless. Just a low camera angle, that looks between the black base and the balls.

[@funky3ddy]

jpopelish I think it's very easy to remove it, unless it's glued. :) I believe they use big camera to film this show, so only mobile phone or small point and shoot will work, but even then, I kinda doubt small camera will be able to pick up entire length without wide-angle lens. Btw, search KZbin for "Pendulum wave (slinger golf)" it should be on blindbrick's channel. That guy made it more stable, so patterns are not as chaotic, and it is much bigger as well.

[@jpopelish]

jpopelish Oh, and lock the camera focus on the 5th or 6th ball from the camera.
