How Well do You Know Your '90s Trends and Fads?

The Reebok Pump had a tiny air pump in the tongue. Wearers pressed it repeatedly, supposedly to increase the high-top shoe's stability, but in reality, it didn't do much.

Many girls took to "crimping" their hair with a special iron, which made crinkly waves. Like so many hair trends, this one could actually damage the hair.

In 1993, Ty Warner Inc. unleashed a plague of bean bag animals called Beanie Babies. The small toys began selling for huge fortunes on the secondary market.

Foreman began doing infomercials for a type of electric indoor grill. Unlike many fads, this one actually started a trend that's still going strong today.

OK, so Bob the Bacteria wasn't one of the original nine Beanie Babies, which included classics such as Spot the Dog, Chocolate the Moose and Patti the Platypus.

The manufacturer was clever -- it limited supply of some of the Beanie Babies, and demand for those creatures skyrocketed. People paid hundreds or even thousands of dollars for one little toy.

Generra Hypercolor were T-shirts that changed color when exposed to heat. One flaw? The reaction was easy to damage if you didn't carefully wash the fabrics.

Scrunchies were elastic hair ties. Girls went wild for them, in part due to their imaginative color schemes.

The Koosh ball was a rubbery ball with rubbery hairs, and kids went crazy for it. Sometimes you would just sit there and...feel it.

Bleach, whether throughout the hair or just on the tips, discolored many a "do" in the '90s. Some people opted for bleach right out of the bottle. Word to the wise -- bleach isn't really very good for your hair.

In the late '90s, Furby was all the rage. The little toy looked a bit like Gizmo from "Gremlins" and cooed and babbled his way into millions of hearts.

To the horror of wedding DJs everywhere, the Macarena arrived....and then never went away. It was the only song of note by one-hit wonder Los Del Rio.

Slap bracelets are back, and they were big in the '90s, too. Just take the flat piece of thin metal and "slap" it on your wrist -- ta-da! Now you're fashionable.

Tamagotchi was a virtual digital pet. These small, handheld devices had tiny screens that represented a pet that you had to feed and clean up after. Neglect your responsibilities and the poor thing died.

It became a rallying cry for rednecks and skateboarders across the land: "No Fear." Legend has it that in some parts of America, you'll still find tattered "No Fear" stickers peeling from old pickup trucks.

The Lisa Frank line of school products, from pencils to folders, were splashed with artsy designs that appealed mostly to girls. And for years, every girl had to have them.

In the '90s, Doc Marten shoes and boots became outrageously popular. They often stood out thanks to their oversized soles.

If you were a klutz and had a hard time even with rollerskates, the '90s were a difficult era for you...because rollerblades got very popular, and they were tough for many people to master.

Elmo, the baby-talking, crimson demon spawn of all things evil, shot to fame thanks to the Tickle Me Elmo doll. The doll sometimes wouldn't stop laughing, even in your nightmares.

Jennifer Aniston's hair in the sitcom "Friends" made the rounds in the '90s, and it was named after her character Rachel. For a time, every woman seemingly wanted "The Rachel."

Maybe you're asking, "what's a pager?" And we envy you, because it means you probably don't have gray hair just yet.

Fanny packs were virtually inescapable in the '90s. Everyone from toddlers to businessmen wore fanny packs around town as if no one had ever before carried a "bag" in the history of human civilization.

It probably should have been labeled as an illicit drug, but Surge was a Mountain Dew copycat that tasted a bit like battery acid but somehow didn't kill you.

The Sony Discman was a popular compact disc player, and everyone wanted one. "Have you seen these compact disc things, man? They're amazing!"

In the early days of a thing called "email," people would log onto America Online. If one of their pen pals had sent them a message, America Online would triumphantly shout, "You've got mail!"

The Thighmaster was a spring-loaded exercise contraption that you squeezed with your thighs. The commercials were, shall we say, borderline sleazy.

The Seattle music scene exploded in the '90s thanks to grunge. The guitar-saturated sounds of Nirvana, Soundgarden, Pearl Jam and other bands seized music fans in a way that no "scene" has managed since.

Napster was a peer-to-peer file sharing program that gained notoriety, in part because it could be used to distribute copyrighted programs and music. Many musicians, sensing lost profits, spoke out against the technology.

In the '90s, Pepsi removed color from a bland cola and it became a strangely popular product. So popular, in fact, that high demand convinced Pepsi to bring it back decades later.

Capitalizing on the success of its TV-connected gaming console, Nintendo released the Gameboy, a handheld gaming device. It accepted cartridges so that players could swap out the games at will.
