Shrink art, Shrinky Dinks, or Shrinkles is a toy and activity kit consisting of sheets of polystyrene which can be cut with standard household scissors. When heated, the cut shapes become about nine times thicker while their horizontal and vertical dimensions reduce to about one-third the original size, resulting in hard, flat forms which retain their initial color and shape. They reached the height of their popularity in the 1980s and are still available from retailers. They can be used for a variety of things like charms and pins. Most sets are pre-printed with outline images of popular children's characters or other subjects, which are then colored in before baking.^[1]
