While it does look like some odd bong, this "sculpture" is pretty interesting. By placing a candle or flame at the top in the cup, the water in the tube is heated and creates steam and pressure. The pulsing water moves down a smaller tube into the main bulb of the piece, causing the water to circulate and the red spheres to move.
Man that thing would be annoying.
