Toadstool

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 417.7 Hz, 110 cents sharp of G4, 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 the big cap to puff out a cloud of spores. Hands-on: squeeze the cap; it springs back.

These red toadstools with white spots are fly agarics, perhaps the most famous mushrooms of fairy tales. A mushroom is the part of a fungus that pops up above ground; most of the fungus is a web of fine threads hidden in the soil. Fly agarics are poisonous, so they are for looking at, not eating.

Tap it and the big cap dips and springs back, and a cloud of glowing spores puffs out from the gills underneath and drifts away. Spores are how a fungus spreads, like tiny seeds, and one mushroom can let out billions of them. Pick the cap's color in the Splash tab. With ✋ Hands-on on, squeeze the cap and it gives under your finger, then springs back.
