Avocado

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 317.4 Hz, 65 cents flat 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 pop the stone into the other half. Hands-on: lift the stone out and put it back.

An avocado is a fruit with a bumpy green skin, soft, creamy green flesh and one big, round stone in the middle, which is its seed. It first grew in Mexico and Central America. Avocados are unusual: they do not ripen on the tree, only after they are picked.

Tap it and the stone pops out of its half, flies over and drops into the empty half with a thock, rocking it, then pops back home and the first half rocks. Pick both halves, or just the half with the stone, in the Splash tab. With ✋ Hands-on on, lift the stone out of its half and put it back (brought close, it settles into its hollow), or pick up the empty half.
