How do divers make zero splash?
In: Physics
The basic idea is to make a hole in the water, and get your entire body through it.
The smaller the hole, the less water moved, the smaller the splash.
Divers break the surface of the water using the smallest point they can, a pointed finger or toe, with their body in a position that makes them as smooth and streamlined as possible. Once underwater, the arms and legs splay out to create more resistance and stop them before hitting the bottom of the pool.
The perfect body position is useless if you land in a belly flop, they also need to land at the perfect angle. Being off in any direction means your body will hit the edge of the hole, making the hole bigger, making a bigger splash.
If you want to make a big splash, you do the opposite. Cannonballs make you wide, can openers make you long, both are maximizing how big a hole you make.
