The Nano-Tech Japanese Aqua Dance from ThinkGeek uses “an internal nano surface that causes water to hyper-bead with ‘Adesso WR'” to turn water into an “automatic cascading frenzy of beads that zoom and bounce their way to the bottom.” Video after the break.

Simply fill the tank on the top of the Aqua Dance with water then push the pump a few times to pressurize. Turn the lever beneath to control the size and speed of the water beads as they drop repeatedly out of the tank.
