H2Oh!: Water Generating Work
Located on the 1st Floor to the left of the Concourse as you reach the top of the stairs from the Lobby.
This exhibit converts the potential energy of a mass of water above the turbine to kinetic energy and mechanical work -- moving the stairs to lift plastic balls.
You may get wet interacting with this exhibit. Protective clothing will be available. A hand-drier is located on the wall.
