Pretzel

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 1124.7 Hz, 75 cents flat of D6, 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 twist it like a knot and let it spring back. Hands-on: pull one side to stretch it.

A pretzel is a baked bread shaped from a long rope of dough into a loop with a twist in the middle. Before baking, it is dipped in a special bath of water and an alkali, such as lye or baking soda, which gives it its shiny, dark brown crust. Then it is sprinkled with coarse salt.

Tap it and it twists like a knot, all in one piece: its two sides wring opposite ways and its loops fold a little toward you. Then it springs a little past its shape into the opposite twist and wobbles to a stop. With ✋ Hands-on on, pull one side of the loop and the soft pretzel stretches after your finger; let go and it springs back into its twist.
