The hidden siphon in your washing machine

Hidden in the detergent drawer of your washing machine is an extremely clever bit of engineering that you've probably never noticed or even realized needed to be there.

How does a washing machine get detergent, fabric softener, etc. from the tray to the drum? With a hand-made 2D version, Steve Mould explains the physics behind the Pythagorean siphon, also known as the greedy cup siphon. He also goes on to demonstrate how some toilets use a siphon to measure the correct amount of water per flush.
