Taco

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.
