I can't say I'm a cup expert, but I'm quite sure that paper cups (or straws) can be made waterproof if impregnated with wax.

- ccozan 7y agoYou don't need to make them waterproof. How long do you plan to drink a soda or whatever else? My kids are done in max 10mins and they look mostly untouched. I left it for one hour in a hot cocoa though, and it was not intact anymore but still usable to a degree.
- darkpuma 7y agoLet's say somebody gets served their beverage when they sit down, then neglect it until after they're doing eating. In a cold beverage, I'd want a straw to last at least an hour. I don't think that should be hard to accomplish either.
