Confused Sea
Air blowing over the surface of water inside a large Plexiglas hemisphere mimics the action of the wind over the ocean by generating waves. The waves slowly change and build until the entire volume of water is circulating as one wave. Viewers can adjust the speed of the air blower and influence the building of the waves.

Fluvial Storm
Swirling water sculpts elaborate patterns of underwater dunes.

Geysers
The timing of the eruptions of these geysers depends on water temperature and pressure.

Liquid Litmus
See the chemical reactions taking place in an electrolytic cell, as electricity flowing through a tank of salt water and pH-indicating dye creates zones of acidic (yellow) and basic (blue) solutions.

Tidal Flow
Floating orange arrows turn a series of leftover pilings into a visual representation of water movement into and out of the Bay. As tides rise and fall, the arrows travel up and down the pilings, swiveling to point the direction of the water flow.

Tidal Memory
Twenty-four columns record twenty-four hours of tide water levels.

Vortex
A twist of a knob sets water jets in motion, causing water in this giant cylindrical tank to spin. Soon, a tiny vortex appears at the surface, gradually swelling in size as it snakes downward.

Watch Water Freeze
Ordinarily, water freezes too slowly to be appreciated. Here, polarized light and an ultra cold slab let you watch water crystalize rapidly in real time. The colorful mosaic of ice that forms is different every time.
