Three Drops is a full body immersive simulation that allows visitors to interact with water at three size scales using their shadows. At each scale, different physical forces can be observed. At the macro (human) scale, where gravity is the noticeable force, visitors are showered with water drops from a simulated shower. At the microscale--one thousand times smaller--where surface tension becomes more apparent, visitors play with a beach-ball sized water drop. At the nanoscale--one billion times smaller and time slowed by a factor of one trillion--where electromagnetic forces can be observed, visitors play with simulated water molecules. This simulation gives visitors an opportunity to interact with water at different scales and thereby discover how different forces can be observed at different scales.
