Yo-yo

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 364.3 Hz, 73 cents sharp of F4, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to throw it down; it spins down the string and climbs back up.

A yo-yo is two disks joined by a short axle, with a string tied around the axle. Thrown down, it unwinds and spins fast; the spin keeps it steady, and a little tug on the string makes it wind itself back up into your hand. Children in ancient Greece played with yo-yos of wood, metal and clay.

This one bobs gently on its string. Tap it to throw it: it drops, spinning as the string unwinds, and then climbs back up the string to where it started. Pick its color in the Splash tab. With ✋ Hands-on on, pull the yo-yo down and let go: it drops to the end of the string, spins there and climbs back.
