American Football

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 358.5 Hz, 145 cents sharp of E4, 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 throw a spiral pass.

An American football is a pointed oval ball of leather with a row of white laces along one side for the fingers to grip. It is often called a pigskin, though today it is made of cowhide or rubber.

Tap it to throw a spiral: it flies up nose first, spinning fast around its long middle line, tips over at the top and lands with a wobble. The spin is what makes a good pass: like a spinning top, a spinning ball holds its direction and cuts cleanly through the air. Pick the color of the leather in the Splash tab.

Made in Splashery. Its code is MIT.
