Tulips

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 605.1 Hz, 48 cents flat of E♭5. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to open the tulips to the sun. Hands-on: push a tulip; it sways back.

Tulips are spring flowers that grow from bulbs, each stem holding one cup-shaped flower. They first grew wild in the mountains of Central Asia. In the Netherlands in the 1600s, tulip bulbs became so prized that a single rare bulb could cost as much as a house.

Tap it and the three tulips open wide to the sun one after another, each petal turning out to show the dark stamens and the pale pistil inside, then they close up again. Real tulips open like this in warm sunshine and close again in the cool of the evening. With ✋ Hands-on on, push a tulip and it bends on its stem; let go and it springs back and sways.
