Floating & Sinking Experiments for Density

Density is often measured by whether an object floats or sinks in water. Real Japanese 1 Yen coins are made from aluminum and can be made to float on the surface of a cup of water. We have Super Dense Wood that sinks in water. Powered by baking powder, the Diving Submarine dives and surfaces just like a real submarine.
