Have you ever wondered why some objects float on top of the ocean, and other objects sink to the bottom? It has to do with the density of the objects compared to the density of the salt water surrounding them in the ocean. If you add salt to plain water, it increases the density of the water. In fact, if you add enough salt, you can make the water so dense that an egg will actually float in it! Explore how this works in this science activity. Read more
