Before mp3 players and iPhones, there was the Walkman. Revolutionary in its time and nearly universal among teens of the '80s, it's now a relic today's children simply can't understand.

In this video, kids are given a Walkman and try to figure out just what the heck it is.

From trying to open it to inserting the cassette to laughing at the headphones, it's funny to watch these youngsters who look at this form of technology the way the previous generation eyed 8-tracks.

And just think -- there will probably come a day when these kids have kids who will be stunned their parents used a phone to listen to music instead of, you know, just thinking of a song and having it automatically play.
