Slime (also called GAK or Flubber) was first created by Mattel toys in 1976. Like the name implies, it was designed to be gross with a glossy green shine and cold slimy feel to it that would ooze all over the place. The product even came sealed in mini green plastic "trash cans." The trash cans had lids on them to keep it from drying out. Parents and teachers hated it, but kids loved to play with it and get into mischief. From pretend "nose snot" to getting a person to accidently dip their hand in a bowl of it, slime had all sorts of fun pranks that could be played with it.
