Dyzzleberry Dictionary ::

A material designed to integrate with a plexi wall of an animal habitat. When a hand or object presses through it, the flexichem seals around the protruding object while items are deposited to or removed from this double-walled, flexible, self-healing polymer. The chief of genetics bent near the ground before he let go of one hand on the crucible and gently pressed an entry spot in H-4’s flexichem. The double-polymer wall of the habitat gave way to the pressure of Dorf’s fist, allowing space enough for hand and crucible to enter. (17)
