Beads' Fountain Effect


Watch the above video clip.  Why do you think the beads "rise up in a curve, like a water fountain, as it falls?"

I think that the beads "rise up in a curve, like a water fountain, as it falls" because when the beads go up and bumps the top of the bottle, it makes itself go upward or in any other type of shape, the momentum also makes the shape go higher.

I think the beads "rise up in a curve, like a water fountain, as they fall” because, if you give the beads a hard enough pull, the first bead will fall out. But if the first bead on the string falls out, then what would the other ones do other than fall out as well? Nothing is the answer. I think that they curve like a water fountain because the momentum from the pull that the guy gave the first part of the string of beads makes the shape go higher.

( I think. )

I think the beads "rise up in a curve" because when the man lifts up the chain and throws it down, he creates the shape and because of the speed of the throw it goes in that shape and the momentum from the speed continues to fall in that shape. essentially if he had infinite beads in that jar it would be a perpetual motion machine.

I think the beads “rise up in a curve,like a water fountain, when it falls” because of the gravity pulling it down after the first couple inches of the beads fall from the power of the pull. To explain how they create that waterfall like shape, the momentum of the first beads makes a weird shape that curves as it falls


One thing I have to add: Who has time to make a 8,000 bead rope, like seriously?! Its as crazy as people keeping track at how many people come in the Eiffel tower and then giving a cake or something to the 25-millionth guy.

I think the beads make a fountain, because when the beads get pulled down, the weight the beads are heavy because they are metal which would be strong enough to pull down the rest of the beads so they get out of the jar. I think the beads also make it go up and out because one beads forces another bead to pull up and out of the jar which forces all of the other ones to go out one by one. I think that if you don’t pull it hard enough, it won’t pull much of the beads out, and I think if you pull it hard it will go out faster and the waterfall would be bigger will be higher

First off, I wonder how he discovered the beads would do that? I mean, why would he bead 8,000 bead on one chain? He must of had a lot of spare time! I agree with Ronan, it is as crazy as keeping track of how many people visit the Eiffel Tower! Good Job tying it into our WITW, Ronan!

I think that the beads stacked upon each other but instead of falling down straight away, the speed of the movement let the beads stand up. The reason that the beads made a waterfall effect is because of gravity. You can stack blocks but eventually they will fall over, so as soon as the stack of beads got too high they fell over. The reason they didn't fall straight is because of the string; it moulded the chain into a sort of waterfall after words.

Have you ever noticed how a strand of string never lines up exactly when you fold it? That is why I believe the string helped mould it.

People do that? (With the Eiffel tower, not with the beads.)

My comment was to Ronan by the way.

I think that the reason that the beads behave so strangely is because of how the beads are packed together. Maybe they turn stiff because of the way you turn it, how the edge of the beads touch another beads’ side, causing the beads to only be able to bend slightly. Since they can only bend like that, they would have to turn slowly or if they had a lot of space they could move up and sideways at the same time. Since the momentum of gravity causes it to move fast, it would have to move quickly, causing it to stretch up and around. (confusing...)

I'm just going to add somethings to my response: I think that the beads "rise up in a curve, like a water fountain, as it falls" because when the beads go up and bumps the top of the bottle, it makes itself go upward or in any other type of shape, the momentum also makes the shape go higher. The beads also are heavy, so they fall down and as I said earlier, the hit the cup hard, and the more the bead falls down, it gains momentum, so the hits are harder on the cup, so therefore it makes the beads go up higher and makes a water fountain-like shape.

I think that the beads "rise up in a curve, like a water fountain, as it falls" because in the beginning when (I presume) you pull the end of the beads, gravity pulls the beads down, therefore keeping the chain moving. The beads rise in a curve because of the force pulling the beads.
