Iceberg

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 478.8 Hz, 146 cents sharp of A4, 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 break off a chunk into the sea.

An iceberg is a huge piece of ice that has broken off a glacier or an ice shelf and floats out to sea. It is made of fresh water that fell as snow long ago. Ice is a little lighter than seawater, so an iceberg floats, but only about one tenth of it shows above the water.

When a chunk breaks off, it is called calving. Tap it and a chunk cracks off, showing fresh pale ice, and tips into the sea with a splash of spray and rings of ripples. The chunk bobs, and the iceberg, now lighter, bobs and rocks. Then the chunk melts away and the splash grows it back.
