Uranus

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 447.8 Hz, 30 cents sharp of A4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to roll it on its side like a wheel.

Uranus is the seventh planet from the Sun, an ice giant colored blue-green by methane gas in its air. It is tipped right over on its side, with its axis tilted about 98 degrees, so it rolls around the Sun like a ball. In 1781 William Herschel found it, the first planet discovered with a telescope.

Here its thin rings turn slowly all the time. Tap it and it rolls like a wheel, to the right and back again. A year on Uranus lasts about 84 Earth years, so each pole gets about 42 years of sunlight and then about 42 years of dark.

Made in Splashery. Its code is MIT.
