i think it works by the weight of the beads falling pulling the ones still in the beaker, so its gravity more or less :), still pretty cool :D

That's awesome!
Physics for the win :)

Basically there is a lot more force on the beads going down (because the string is longer) but the beads going up have to be moving at basically the same speed. So the beads leaving the jar have some upward momentum that gravity has to over come. Thats how you get the cool arc (i) 8-)

Does someone has a real explanation, because I'm not really convinced by your "I think blablabla gravity blablabla momentum...".

Edit: Ok, nobody seems to really know : http://www.reddit.com/r/askscience/comments/1gza0c/selfsiphoning_beads_why_do_they_behave_so/capiutx?context=3

There is a very strong magnet (maybe even electro) just out of the top view of the camera. I would guess it probably took quite a few tries to get the positioning right.

#10 That would be even more awesome

#10 Come on, at least it makes sense that the gravity is pulling it down (without explaining the loop), but what magic force could make it raising up?

#12. The video was filmed upside-down.

#1, worst explanation ever. = "it falls because... gravity"

I saw something like this in New Orleans only at the end of the beads I got to see boobs.

I wish I was smart enough to calculate the phenomenon using physics computations...8-)
