Abstract
A toy with a portion of apparently changeable color includes a normally upright and invertible elongate figure defining a normally opaque upper chamber and an at least partially transparent normally lower chamber. A valve in the figure is movable between an enabling position and a disabling position to control fluid flow communication between the chambers. A volume of colored fluid is disposed in the figure and capable of flowing between the chambers via the valve under the influence of gravity only when the valve is in the enabling position. A spring biases the valve towards the disabling position, and a manually operable portion moves the valve to the enabling position. Inversion of the figure (so that the normally upper chamber is below the normally lower chamber) and manual operation of the piston moves the value into the enabling position and thereby enables the flow of the volume of fluid under the influence of gravity from the normally lower chamber to the normally upper chamber where the fluid is visible through the transparent portion.
