The magnetic kangaroo (or rabbit, or whatever else the kids decide to make it) bounces not on a spring of metal, but on completely invisible magnetic flux.
This project is perfect for very young kids (I do it with kindergarten and first graders).
Magnets are harnessed throughout modern life (motors, generators, television, compasses, computer memory, microwave ovens, audio and video tape, speakers, etc). Then there is the that pinnacle of human invention without which civilization would collapse in utter chaos: the refrigerator magnet!
If you are just making few of these, each project will cost over a dollar, but you can get the magnets at a nearby Radio Shack. For instructions for making just a few magnetic kangaroos, click here.
If you are doing this with a big group of kids, it makes sense to get the magnets mail order at less than half the price of Radio Shack magnets. For slightly different instructions for making magnetic kangaroos with a large group, click here.

I'd like to know how this project goes for you. I'm happy to answer questions about it. Feedback from you is an important way for me to know what works and what needs clarification.
