Kinetic sculpture uses water, air bubbles, and a toilet flush mechanism

Take a look at this fantastic sculpture by Andrew Smith titled Exhaler V. The piece features an enclosed water tank inside of which a capsule is slowly lifted by a stream of air bubbles. Upon breaking the surface of the water at the top, a toilet flush mechanism is triggered, causing the capsule to descent again so the process can be repeated. Very inventive!
