At the Toronto Toy Fair of 1990 a new children’s play product was introduced by its creator, Toni McKee. She got the idea from her university class in which she studied different types of chemical suspensions. One such suspension had molecules that would bind to a certain extent yet come apart easily, melting into a liquid when it was handled. “I got the idea of making it into a children’s toy,” McKee stated (BC Woman, October, 1990, p. 13). McKee soon found business partners, consulted with chemists, and came up with a toy which she named GUK. Later McKee assigned her rights for GUK to Pyewacket Enterprises, Inc. of Canada, which registered it with the US Patent and Trademark Office on February 5, 1991 as a powdered mixture, which, when mixed with water, becomes a tactile substance for entertaining and educating children.
