Rocket

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 610.6 Hz, 67 cents sharp of D5, 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 launch the rocket.

A rocket flies by pushing hot gas out of its engine very fast. As the gas rushes down, it pushes the rocket up, just as a balloon zooms off when you let its air out. A rocket carries its own oxygen to burn its fuel, so unlike a plane it can fly where there is no air at all, out in space.

Tap it to launch: the arm of the tower swings away, the engine lights, clouds of smoke billow across the pad, and the rocket shakes, lifts off and climbs faster and faster until it is gone. Then a new one stands ready on the pad. Pick its color in the Splash tab.

Made in Splashery. Its code is MIT.
