Pythagoras Cup (Greedy Cup) filled with Mercury

Yeah, even though sometimes i complain about the mathematical formulas and their inventors while I struggle with some  proofs, they are 'reeeally' very useful. This is a cup which is invented by Pythagoras. The basic principle is related to philosophy of live. 'The time, you become greedy to get more and more; you loose everything you have! ' Nice, right. It is more inspiring to me that as a genius he not only worked for mathematics but also thought of fairness and made it touchable! I like this cup. I want to buy one. :)
