The Secret Behind the World’s Best Skipping Stone

Elasticity is key.

Scientists at Utah State University, who apparently take their play time very seriously, acquired a popular Water Bouncing Ball toy and did a bit of research. Using high-speed cameras, they compared spheres of different material bouncing across tanks of water. In a paper published in Nature Communications, the team discovered soft and elastic material made the ideal skipping stone. The team is currently working with the U.S. Navy toward more practical applications.
