the first ball should stop at the surface because the momentum wouldnt be enough to make it pull the other ball of of water

hm there are plenty of balls still under water to drag the one that are off the water.

but i dont think their upward force is sufficient to make the ball on the surface beat the gravity. plus i imagine that they are linked with a loose string so it makes the things even more difficult

well, no actually it shouldnt make it more difficult, because, as the string folds due to the float of the balls, it will pull the string behind and should make the thing move. fuck, it must be fallacious, but im not good enough at physics to find it

maybe it's what i said before - that float x gravity 0:1

the force require to submerge a ball from the "air chamber" is equal to the force exerted by a boyant ball rising, so nothing goes anywhere. Thens theres all the friction and drag which just makes it worse.

someone just report the model to myth busters

u cant use shotgun or an assault rifle when checking if this works so i guess they wouldnt feel like looking into it

How so?

woodbrave is all over the place lol

haha the facebook status was a good laugh

lol wut, somebody explain why the bubble ones wouldnt work? so far no explanation has satisfied me, yes it takes the same ammount of energy to submerge than the lift, but thats why theres the air "chamber" to always have more lifting balls than submerging ones.

the only problem is the seal on the left

well for one thing if the balls of air did move the air chamber would immediately fill with water

but it wouldn't move because there is a hell of a lot of pressure from the water trying to fill that air chamber

lol it's really annoying me that I can't find a way that thing won't work

Haha if that was the only problem, don't you think it would have been solved by now, the whole science/technology world would have been working hard to build a seal that lets this perpetuum mobile work...

Can't really think of an intuitive reason why this can't work, probably the whole chamber displacing all this water creates huge pressure as someone else said and incredible force is needed to force something through the seal to the water around it. And this pressure will increase a lot with depth.
