A mechanical toy having two enclosed chambers, one positioned above the other, connected by a tube; a vaporizing medium contained within the enclosed chambers and tube; means for rotationally supporting the tube and chambers; means for exciting the vaporizing medium within the lower chamber to create an increase in vapor pressure within the lower chamber relative to the upper chamber that exerts force upon the vaporizing medium within the lower chamber to communicate the vaporizing medium through the tube into the upper chamber allowing gravity to act upon the upper chamber when a sufficient amount of the vaporizing medium has collected within the upper chamber pulling the upper chamber downward around the means of rotational support.
