Its note

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 1058.7 Hz, 20 cents sharp of C6. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

How to play

Tap it to spin it on the desk. Pick its color under Look in the Splash tab.

About it

A wooden pencil. The "lead" inside is not lead at all but graphite, a soft gray form of carbon, mixed with clay and baked into a thin stick. More clay makes a harder, lighter line and less clay a softer, darker one; the letters on a pencil tell which: H for hard and B for black, with HB in between.

Tap it to flick it: it spins flat on the desk about its middle for two whole turns and slows to a stop where it began. Under Look in the Splash tab, pick yellow, red, blue, green, black, plain wood or the original scan.
