Taco

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 423.2 Hz, 67 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 it to break the shell in half; then it closes up again.

A taco is a Mexican dish: a tortilla, a thin, round flatbread of corn or wheat, folded around a filling such as meat, beans, cheese, lettuce and salsa. People in Mexico have made corn tortillas for thousands of years. This one has a crunchy, fried corn shell.

Tap it and the shell snaps across the middle with a crunch. The halves pull apart and swing open like a book, showing the filling in each break, and bits drop out of the break onto the plate, bounce a little and slide to a stop. Then they hop back in and the halves close.
