archimedes' law
Do you see the man sitting on top of this tanker truck? He gives you a sense of how big the truck is. Whats behind the truck? Is it a huge apartment complex? Its just as massive as a very large building, but its not even resting on land. Its a giant cruise ship, and its floating on water. The ship weighs about 100,000 metric tons. How can such a tremendous weight float on water? Why doesnt it sink to the bottom of the ocean instead? Archimedes law explains why.
