Knight's Helmet

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 414.1 Hz, 95 cents sharp of G4, 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 open the visor; tap again to close it.

A knight's helmet was made of steel, hammered into shape by a skilled craftsman called an armorer. The front piece, the visor, has narrow slits and holes to see and breathe through, and it swings up on pivots at the sides so the knight could show their face. Plumes of colored feathers on top made the knight easy to spot at a tournament.

Tap it to open the visor, and tap again to close it. Pick the color of the plume in the Splash tab. A full suit of steel plate armor weighed about 20 to 25 kilograms (45 to 55 pounds). With ✋ Hands-on on, lift the visor on its hinges yourself: raised all the way it stays up; let go lower and it drops shut with a clank.
