Waterfall

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 348.3 Hz, 95 cents sharp of E4, 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 send a surge of water over the falls.

A waterfall forms where a river runs over a steep drop, often where hard rock sits on top of softer rock. The falling water wears away the softer rock below, so over thousands of years many waterfalls slowly move back upstream. The tallest on Earth, Angel Falls in Venezuela, drops nearly 1 kilometer.

Tap it to send a surge: a front of white water runs along the river and over the edge, a thicker sheet of white water pours down the falls, foam spreads over the pool and a cloud of mist billows up, then it all calms again.

Made in Splashery. Its code is MIT.
