Float's Dance Party
How does a toilet flush itself?
You press the handle, you walk away, and the toilet does its thing. But wait — how does it know when to stop? There's no tiny brain in there, no batteries, no little robot saying "Okay, that's enough water!" So what's going on?
The secret lives in the tank behind you. Lift the lid and you'll see a surprisingly simple machine: a few plastic parts floating in water. The star of the show? A balloon-shaped thing called the float. Right now it's sitting on top of the water like a beach ball in a pool.
