Fountain video documentation

This piece drips paint into a bowl of water. The water is occasionally stirred for the visual effect of swirling the paint and also to help dissolve it. The paint is dripped when a motor driven assembly opens a valve while the liquid is stirred by a motor driven propeller.

This piece was constructed using LEGO Mindstorms programmed using the LegOS system. It was constructed from various LEGOs pieces gears and motors and included additional materials: a brass ball valve, pipe, nozzle, and plastic tubing. The pigment is diluted poster paint that drips into a bowl of water.
