Buoyant Betting


A bunch of my friends were hanging out at the park. The girls were sitting on the merry go round, laughing at the boys who were having a macho contest. They wanted to see who could carry the heaviest cement brick across the field. Finally, they got to the heaviest block, and neither of the could carry it all the way across, dropping it on their feet and yelling out in pain. Laughing, I bet that i could easily carry it the distance of the field. They happily took the bet. We drove down the street to the beach and I told them to throw the rock in the water. It was very easy for me to carry it the distance of the field. I collected my winnings and thanked physics! Instead of carrying the whole weight of the rock, I was helped with buoyant force (equal to the weight of the salt water displaced) So I only needed to carry W-Buoyant Force. Yay!
