Bicycle

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 2452.5 Hz, 1074 cents sharp of E6, 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 ring the bell and spin the wheels.

A bicycle has two wheels, one behind the other, and pedals that turn a chain, which turns the back wheel. It stays up while it moves, because the rider keeps steering the front wheel a little under the bike, balancing it without thinking. The first bicycles with pedals were built in France in the 1860s.

Tap it: the bell shakes and rings, the wheels spin through five fast turns, and the pedals go around twice. Bicycles are among the most efficient ways to travel ever invented: a rider uses less energy to go a mile than a walker does. Pick the color of the frame in the Splash tab.
