Aha! Thanks! So I need to find an object that behaves like the ping-pong ball as you said, but not only that, but it's also got to be magnetic. I wonder where I'll be able to buy that :) I'll go and think about that, thanks again !

Alright :D Sorry, I had the feeling I was getting on your nerves there. I'm thinking out loud here: To get that "bubble" mechanic, I will need a rather "dense" liquid, maybe honey or something. I will probably encounter a problem; there is no force that will pull said bubble up, gravitation...

I thought about a second magnet, that pushed the other away, but that makes no sense. Secondly, I thought about some kind of bubble mechanic, but that sounds impossible. So, it may be obvious, but I can't see it :(...

Any hints? I haven't found a thing that could be it... Sorry .. :/

Yes, There was a magnet outside of the tube. The magnet moved up in a straight line, thus it went against the gravitational force. The tube was around 50 cm/ 20 inch long, with a circumference of around 5 cm/ 2 inch . Also noteworthy: the speed was constant, so no acceleration at all, even in...

Hey! First of all, thank you for answering! Second of all; no, I was not able to see the inside. Do you have any idea for a program I can use to send a sketch? Again, thanks a lot for helping me out here! :)

And as the magnet on the inside is pushed up, and is "connected" with the magnet on the outside, he takes the magnet on the outside with him.

1. So, during one of my classes, the teacher showed us a small experiment, and asked us to explain how it works. The experimented consisted of a tube, closed on both ends, and attached to said tube is what I think is a magnet. Now, everytime he rotated the tube, the magnet rised to the top with...
