Tim and Adam made a bet.Tim bet Adam that he could put something into his barrel to make it lighter. They first weighed the barrel. Then Adam left the room while Tim pondered a solution.One hour later, Adam returned, and they weighed the barrel once again. The barrel was indeed lighter. What did Tim put in the barrel?
well i have one thing in my mind.........what if the hole is made at the upper part of the barrel instead of the bottom ?????? is that going to make the barrel lighter too if the barrel is half full (and the hole is made in the upper half of it) ???????
think think ??????
