This might sound like a stupid question, but in my physics class we have a game called "Will it float?" It's just like on the tonight show. We pick out random things to put in the water and guess if they'll float or not. My teacher decided to let us try to stump her after several weeks of her trying to stump us. If we get her, we get 5 bonus points! I've been trying to think of things that are guaranteed to stump her and have tried something, but to no avail. She's too good for us! Does anyone have any ideas on things that would almost definitely seem to float but then sink or vice versa??
