Soap Bubbles

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 939.0 Hz, 12 cents sharp of B♭5. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to blow a stream of bubbles.

A soap bubble is a very thin skin of soapy water wrapped around some air. The skin pulls itself as small as it can, and the smallest skin that can hold the air is a sphere, so bubbles are round. The swirling colors come from light bouncing off the inside and outside of the skin, which is thinner than a hair.

Bubbles drift up slowly from the wand by themselves. Tap it to blow, and many more stream out faster, float away and fade. Pick the color of the wand in the Splash tab.
