This week finds photographer Bob Elbert at the top of the raindrop tower in the National Soil Tilth Laboratory.

The raindrop tower is an open shaft spanning four floors that simulates falling rain for experiments in soil erosion, soil penetration and water runoff. Scientists such as Dan Jaynes (pictured) are able to control the rate of rain and, to a lesser extent, the size of the raindrops falling in the tower.
