What is Buoyancy?

Buoyancy is the upward force that keeps an object afloat. This video shows how an object floats in fluid at a level where the weight of fluid displaced is the same as the weight of the object itself.

Floating stone fountains shoot water up under the stone at high pressure to create a stunning effect.

Here's another great explanation of buoyancy with a simple experiment you can try at home using clay and water.
