Blackberry

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 301.3 Hz, 56 cents flat of E♭4, 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 burst off its drupelets.

A blackberry, like a raspberry, is a cluster of many tiny, shiny fruits called drupelets, each with a seed inside. Blackberries grow wild on thorny, tangled bushes called brambles, and ripen from green to red to deep black.

Tap it and half the glossy drupelets burst off, bounce on the table and glint, then spring back. Unlike a raspberry, a blackberry keeps its soft white core when you pick it, so it is solid all the way through instead of hollow.
