Woah. 

Cannot stop watching!

wow!!  this is so cool!!  i love the use of magnets!  and the spaghetti as levers!!  and the different weights of the glass and metal marbles making them behave differently!!!  so cool!!!!!!

i love how everything takes turns. the sequence that starts at 2:39 is tops!! and i love the pinball action in the penultimate scene.

Me too!

I anthropomorphize the marbles and wonder what it must be like to be a marble going through that. 

Spaghetti as levers was pretty wonderful too.
