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.
Here you can select and photograph a precise moment—to within a millisecond—as a water droplet falls into a small pool of water. Freezing the action reveals both the complexity and the beauty of fluid motion.
