Why do some things sink while others float?  Why does a gallon of rubbing alcohol weigh less than a gallon of water?  Why do some things float in seawater, while they sink in fresh water?  Let’s find out!

In this simple lesson you’ll learn all about buoyancy and density, and how density affects what will float in water and what will sink.  Experiment by sinking an egg in water...then getting it to float!
