Kids go crazy for the darndest things. Just last winter, it was Zhu Zhu Pets. And recent history is littered with Pogs, Pokemon, Beanie Babies and Cabbage Patch dolls. Occasionally, as with Silly Bandz, a fashion trend will start and end with the playground set.

Remember:

Friendship bracelets: Little girls would go to the craft store, load up on embroidery floss, then go home and weave and braid themselves silly, crafting creations to hand out to their favorite people. Boys and girls wore them for months, until the thread became too filthy, frayed or stinky to keep. The craze peaked in the 1980s but still flares at summer camps and particularly groovy Grateful Dead revival concerts.

Slap Wraps: If you were a kid in the '90s, you probably begged for a bracelet that looked like a Venetian blind and sounded like an especially lively box of rice cereal: The Slap Wrap. A thin, bendy piece of metal covered in fabric, it would snap — with a thwack noise — over a child's wrist. It was all good fun until teachers complained about all the noise, and the metal starting cutting into kids' arms.

Friendship pins: If you didn't have these attached to your Keds in the 1980s, you probably didn't have any friends. Nothing more than tiny colored beads painstakingly guided onto everyday safety pins, these nonetheless were one of the more pervasive trends of the decade. The best part: The colors were all fraught with meaning.
