Many people have learned to throw skipping stones across a pond or lake, but how many have considered the physics of how it happens? In this video, researchers use high-speed video to explore the skipping of various balls across water. The deformation of the ball as well as the shape of the cavity its impact creates determines whether it rebounds off the water’s surface.
It’s time for some nerdier stuff on this blog. :)
