Real Croissant

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 478.0 Hz, 43 cents sharp of B♭4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

A croissant is a flaky, buttery pastry shaped like a crescent moon, and "croissant" is the French word for crescent. Its dough is folded around a slab of butter again and again, which makes dozens of thin layers. In the hot oven, water in the butter turns to steam and puffs the layers apart.

Tap it and it tears in half to show the soft, layered inside, a puff of steam rises, and then it closes up again. Croissants are a favorite French breakfast, but the idea came to France from Vienna, in Austria.
