Beach Ball

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 264.7 Hz, 20 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 toss it up. Hands-on: toss it and it floats and drifts down.

A beach ball is a thin plastic ball blown up with air, usually with bright stripes of color. It weighs so little for its size that the air slows it down almost at once, which makes it easy and safe to play with.

Tap it and it is punched up: it rises, slows, then floats down slowly, drifting and turning lazily, lands softly with a wobble and bobs to a stop. Pick its three colors in the Splash tab. Air pushes on every ball as it moves, but a light, big ball like this one feels it the most.
