Getting a drink of water would be very different if you were the size of a doll.

Where: Crossroads: Getting Started
The timing of the eruptions of these geysers depends on water temperature and pressure.
Where: Gallery 4: Living Systems
Like comets, these chunks of dry ice slowly disintegrate as they move, leaving a visible trail of condensed water vapor.

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.

Rust is a major issue in waterfront buildings, as water enters cracks in masonry structures and rusts the underlying steel reinforcement. This exhibit shows the expansive force of rusting steel. A piece of iron placed in the cleft of a block of concrete is beginning to rust—it will expand over time and eventually fracture the block.
Where: Koret Foundation Bay Walk
