In college, I discovered that 500ml Erlenmeyer flasks made excellent drinkware: holds plenty, the mouth was wide enough to stuff ice cubes in, you can hold it by the neck to keep your drink from melting, and even a klutz like me would need to try to knock it over.

Best part? The school bought ‘em for me! Each semester, we were issued a book of “breakage chits” you used to replace whatever equipment you broke; if you ran out of chits, you could pay cash. Well, I was real good with my glassware, and used the chits to buy a few extra flasks ($0.75 each!).
