Why does a ship float in the ocean but a quarter sinks when you throw in the ocean?
A quarter is solid metal. It is heavier than water of the same volume. A the metal in a ship only covers the outside. The inside is air. Let's do an experiment: We will take a soft drink. We will drink the contents of the can. We will look at the can. It is empty. The walls of the can are solid metal. The inside is air. We place the can in a bowl of water. Does it sink or float? Guess what? It floats! Bravo! Viva! Viola! Now we take that same can and fill it with water. We are seeing if the can floated because the metal surrounded air or if it floated because the metal itself floated. Guess what, the can sank glug, glug. The can floated because it consisted of metal and air. It did not float because steel floated.
