Hello, my name is Joshua. I am The Homeschool Kid.
Today I am going to show you one of my favorite science experiments. It is called the Cartesian Diver. The Cartesian Diver is a very classic experiment. It is named after a french philosopher and mathematician named Rene Descartes.
This science experiment demonstrates Archimedes' principle. According to The Usborne Science Encyclopedia, "Archimedes' principle states that the upthrust acting on an object is equal to the weight of the fluid that the object displaces. This means that the spays the object takes up the more fluid it pushes aside.
Watch this video if you would like to make it.
Stay tuned for more fun science experiments.
