Geyser

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 515.7 Hz, 25 cents flat of C5. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to make it erupt.

A geyser is a hot spring that now and then shoots water and steam high into the air. Deep underground, hot rock heats water trapped in narrow cracks until it boils and bursts up out of the hole. The word comes from Geysir, a famous geyser in Iceland.

This geyser bubbles by itself, with a bigger eruption every so often. Tap it to make it erupt, shooting up a plume of water in a cloud of steam. The bright colors around its pool are mats of tiny living things that love hot water. More than half of the world's geysers are in Yellowstone National Park.

Made in Splashery. Its code is MIT.
