swestrupShe posted a physics conundrum in her journal, so I've decided to post one of my favorites:
A swimming pool full of water has a row-boat floating in it. The rowboat is just barely managing to float (the boats sides are almost underwater) because a large lead weight is sitting in the boat. The slightest wave will spill water into the boat, causing it and its cargo to sink to the bottom of the pool. If this happens, after all the waves have settled down, will the level of the pool have gone up, gone down, or stayed the same?
