Mars pool waves rise 1.6x higher, so cannonballs make bigger, slower splashes

Using an idealized wave model, Owen Lewis works out what a Martian swimming pool would look like: with Mars gravity at 38% of Earth's, waves stand about 1.6x taller and travel at 0.6x the speed. A cannonball jump would send the splash higher and let it fall back more slowly — bigger splashes on Mars.

Commenter Igor Carron, who says he has worked in simulated Martian gravity, notes the difference is barely noticeable in practice.
