Why was gak invented?

Gak was invented in the early 1990s by the toy company Mattel as a fun, squishy, and stretchy sensory toy for children. It was designed to provide a tactile experience that would engage kids in imaginative play and creativity. Gak quickly became popular due to its unique texture and the ability to make interesting sounds when squished or stretched. Its appeal has since made it a nostalgic item for many who played with it during their childhood.
