Tennis Ball

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 267.5 Hz, 38 cents sharp of C4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to slam it down and watch it bounce high.

A tennis ball is a hollow rubber ball filled with air under pressure and covered in fuzzy felt. The felt slows the ball in the air and helps the racket's strings grip it for spin. Bright yellow balls came in during the 1970s, because they are easier to see on television.

Tap it and it is slammed onto the floor: it squashes hard, shoots up high with topspin, the fuzz fluffing out at each hit, and bounces a little lower each time. Pick the color of the felt in the Splash tab.
