French scientists have investigated the physics of stone-skipping to learn the best throwing angle, speed and spin. They built a unique stone-skipping machine that shows the key to maxing out your rebounces is lofting the rock onto the water at a 20-degree angle. This "magic angle" proved to be far more important than either speed or amount of spin.
Other tips to make you a super stone skipper:
- Choose a flat, round stone.
- When you throw, put some spin on it.
- Throw with the wind, not against it.
