  • Patent number: 6589096
    Abstract: An apparatus and method for creating and destroying toys having a solid exterior and liquid interior are disclosed. The apparatus and method entail the creation of an impression within a supply of modeling compound using a form having a desired shape. The impression formed within the modeling compound is then filled with a curable liquid which cures upon contact with the modeling compound. The modeling compound remains in contact with the curable liquid for a sufficient length of time to cure an exterior skin while leaving the interior in a liquid state. The liquid interior is then drained and refilled with a non-curable liquid so as to provide a toy having life-like features. The kit further provides a crushing mechanism having a movable plunger adapted to physically crush the toy by rupturing the exterior skin and splattering the liquid interior against a dome of the crushing mechanism.
