Buzz Balls and Chatter Stones are Magnificent, Magnetic Marvels

I read somewhere that Einstein was fascinated with magnets. I can honestly say that I share his fascination. There is just something cool about them. Buzz Balls and Chatter Stones are super strong and shiny magnets that are fun to play with. The concept is simple enough: you toss them up separately, and when they collide they make a funny noise.
