Spinning Top

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 462.5 Hz, 14 cents flat of B♭4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to spin it faster; it wobbles more, then steadies.

A spinning top is one of the oldest toys in the world, played with in many lands for thousands of years. While it spins fast, it balances on its tiny point, because a spinning thing holds the direction of its spin. As it slows, it starts to wobble, and its handle traces a slow circle; scientists call that circling precession.

This top is always spinning. Tap it to spin it much faster: it tilts and circles more widely for a few seconds, then settles back to a steady spin. Pick one of three sets of colors in the Splash tab.
