Learn about the power and properties of water

Learn what waves are, how they form, and how they affect sand and shore at the Wave Tank, 14-foot interactive tank filled with 1,000 pounds of water and 150 pounds of sand. Try out a Water Cannon and play with laminar flow—a hypnotic variety of fluid flow that takes place when a stream of water is undisturbed by air turbulence. At the Water Bells, learn about cohesion, the characteristic that seems to make water mysteriously “sticky.”
