Star

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 418.1 Hz, 88 cents flat of A4, 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 to run the star's life, sped up. Pick the kind of star in the Splash tab.

A star is a huge ball of hot gas that shines because, deep in its core, it squeezes hydrogen into helium and gives off energy. Its color shows how hot it is: red stars are the coolest and blue stars the hottest. The Sun is a yellow star, about halfway through its life.

Tap it to run the life of a star like the Sun, sped up. It swells into a red giant, puffs off its outer layers as a glowing shell and shrinks to a tiny white dwarf; then a new star lights up. A real star like the Sun takes about 10 billion years to do this. Pick the kind of star in the Splash tab; a tap always plays the Sun's story.
