– Try strange stones and see what happens, mathematician Ryan Palmer of the University of Bristol tells the newspaper The Guardian.
Palmer and his colleague Frank Smith, who is a professor of mathematics at University College London, found that certain types of stones can produce longer, more dramatic bounces if used for fishing bounces.
Especially the potato-shaped stones are put forward as well adapted, according to the researchers and their new mathematical model.
The two researchers created the model to study how an object’s shape and mass affect how it bounces off the surface of water.
Beyond the important importance for future fish bounces, writes The Guardian, the model will help researchers work on problems such as ice and frost on high-flying aircraft, and provide insight into the forces in play when planes land on water.
Until then, anyone can try bouncing heavier potato-shaped stones.
– If you have a heavier rock, you can get a superelastic response, where you get a single mega-bounce instead of multiple small ones. It’s a game-changer. It’s very satisfying when you do it, says Ryan Palmer.
