Tennis ball and spray. High-speed photograph of spray produced as a wet tennis ball with backspin travels through the air. The rapidly rotating ball produces a centrifugal force that pushes water to the equator of the ball and then flings it outwards as a radial spray.

Tennis ball and splash. High-speed photograph of the splash produced as a tennis ball bounces off a wet surface. As the ball impacts the ground, it deforms and displaces a ring of water, which rises up in the shape of a crown, or corona.
