Visitors pull on a rope, raising a wedge-shaped sled up a ramp. As the visitor releases the rope, the sled slides down the ramp and into the water, creating a wave. The wave propagates across the tank, cresting and splashing up a beach that is actually a ramp rising up from the bottom of the tank. Along the beach are a few scale model houses. As the wave reaches the "shoreline", it begins to break and crashes over the houses. A camera records the events and with the push of a button the wave crash can be replayed at a slower speed to match the scale of the houses. The video is played back several times before it resets to a live feed. Designed with technical tsunami input from Dr. Philip Watts.
