Bacterium

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 636.8 Hz, 60 cents flat of E5, 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 make it divide in two. Try the Swim slider in the Splash tab.

A bacterium is a living thing made of just one small cell, with no nucleus: its DNA floats inside it. This one is rod-shaped, with long whips called flagella that spin like propellers to push it along. Most bacteria are harmless, and many help us, like the ones in our gut that help digest food.

Tap it and it divides in two, as bacteria do: it pinches in at the middle as a new wall closes across it, its DNA is shared between the halves, and the two cells come apart. Then the splash slides them back together. Some bacteria can divide every 20 minutes. Swim controls its swimming motion and Color sets its tint.
