Greed Cups
PIRA: 2B60.20
Materials: Greed Cup, Water
This demo is to show one way a siphon works. When the cup is filled it can be filled halfway without spilling because it does not go over the apex of the siphon. Once the cup is filled too much the liquid will have gone over the apex of the inner tube creating a siphon in which case the liquid will be drained completely.
