Pythagorean cup

A Pythagorean cup is also called a Greedy cup. If you pour over the tube in the middle, it will all drain out.
But if you don't pour over the tube in the middle, you will be able to drink what you poured into the Pythagorean cup.


Application: If your an adult, this is a good idea for you: If you were at a party, and they had drinks and beer and stuff like that, and you don't want to get drunk, bring a Pythagorean cup. You will not be able to drink an over-load of alcohol and then you wont get drunk!!!!!!!
