Glass Bong Einstein
E=mc² is pure simplicity compared to this highly sophisticated Glass Bong Einstein. Well, at least it helps you ponder thoughts about the theory of relativity - depending on the adjustment of the five chambers it is relatively small (26cm) or big (40cm), but the smoke is always smooth and very cool and clean. And then it is time to calculate the impact force: E=½m x v² - holy physicist!
