The Real Levitation
This frog defies gravity with diamagnetic levitation--many materials that we ordinarily think of as non-magnetic are actually diamagnetic and can be manipulated using magnetism. Learn about several kinds of magnetic levitation at The Real Levitation, and see why frogs were used here.
It's easy to show that grapes are diamagnetic--just see this Exploratorium snack. For an explanation of diamagnetism, see the text at the end of the snack.
You may have seen the Levitron, the spinning and levitating top, in a physics classroom before. Read about how it works here.

Exploratorium: Snacks about Magnetism
Try any of these experiments from the Exploratorium to learn more about magnetism. Many of them use household items; some equipment may be more difficult to find. Have an adult help you.
You might also want to try making a ferrofluid like the ones in the From Physics Research feature above. Again, get help from an adult.
