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.
In this TED-Ed talk, UC Berkeley biologist Robert Full describes the unlikely way he studied gecko’s feet and how these beneficial discoveries could eventually save lives. The Ted-Ed Lesson includes a short quiz to follow the video, and additional links that go deeper into Full's work.
