What is special about these magnets?

In addition to their unusual shape and smooth polished surface, these magnets can be quite the noise makers! Simply take the pair of magnets and separate them, placing one in each hand. Then, carefully toss each magnet into the air about 12 inches, aiming to have them collide in mid-air. Upon impact the magnets will vibrate rapidly creating a "buzzing" or "clicking" sound. Some people compare the sound to a locust or cicada. It's loads of fun and a great way to improve motor skills and hand eye coordination!
