Drip

open the tap slowly. count the rhythms.

a leaky faucet period-doubles its way into chaos

This faucet’s drip timing runs on the same simple feedback equation, known as the logistic map, that shows up in population growth and other real systems: as flow increases, one steady rhythm splits into two, then four, then more, doubling its way toward a pattern that never repeats. That period-doubling route into chaos isn’t unique to this toy; it turns up in plenty of real physical systems too.

same route — period doubling — leads to chaos in real faucets, hearts, and lasers

Concepts: chaos, rhythm.
