ABSTRACT:
A playball which when manipulated by a player produces a display simulating the flow of lava whereby the player, in effect, has lava on his hands. The playball is formed of a transparent plastic sphere divided at its equator into two half-sections by a partition having several shaped openings dispersed therein. The sphere is filled with a clear oil in which is deposited a charge of water-based syrup having a distinctive color. The syrup which is immiscible with the oil normally forms a pool on the bottom of the lower section of the sphere. When a player turns the ball upside down so that the lower section containing the pool is then the upper section of the sphere, the syrup then impinges on the partition to flow through the openings therein into the section below. In doing so, the flowing syrup simulates rivulets of lava which collect at the bottom of the lower section to reform the pool.
