Flat rocks may not make the most dramatic splashes.

If you want to find a rock that will make the biggest splash possible, you might look for one that’s just a little bit curved, which maximizes the force of its impact when it hits the water, according to a discovery that overturns long-held beliefs in physics.
The discovery was made by Jesse Belden of the Naval Undersea Warfare Center in Rhode Island and his colleagues, who were trying to test the idea that flat objects make the biggest impact on water.
