White Blood Cell

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 267.3 Hz, 37 cents sharp of C4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap it to catch a bacterium and eat it up.

White blood cells are the body's defenders: they find and clear away germs. This one is a neutrophil, the most common kind, which eats bacteria by wrapping itself around them. This is called phagocytosis, which means "cell eating" in Greek.

Tap it and a bacterium swims in from the side. The cell reaches out a cup of its skin around it, draws it inside and closes over it; then tiny grains inside the cell gather on it and break it down until it is gone. Élie Metchnikoff first saw cells eating germs like this, and won a Nobel Prize in 1908.

Made in Splashery. Its code is MIT.
