Patent ID: 8118635

Claim:
An educational mechanical device comprising a pair of enclosed chambers connected by a tube extending into each said chamber wherein said chambers are positioned in such a way that one chamber is situated above the other; a rotational shaft centrally connected to said chambers and tube defining an axis of rotation of the two chambers around the rotational shaft; a vaporizing medium contained within said enclosed chambers and tube; support arms connected at each end of said rotational shaft at bearing points to that provide 360-degrees of rotational freedom; a base secured to said support aims below said bearing points; a heat source about said base to excite said vaporizing medium within said lower chamber and create an increase in vapor pressure within said lower chamber relative to said upper chamber that exerts force upon the vaporizing medium within the lower chamber to communicate the vaporizing medium through said tube into the upper chamber; said chambers are each asymmetrically constructed with respect to a vertical plane running lengthwise through said chambers and rotational shaft to ensure that when the vaporizing medium collects in the upper chamber a weight imbalance occurs; when a substantial amount of the vaporizing medium collects in the upper chamber creating the weight imbalance within the upper chamber gravity acting upon the upper chamber pulls the upper chamber downward around the axis of rotation creating rotation in the direction of the weight imbalance effectively switching the position of said upper chamber with said lower chamber; said heat source acting upon said lower chamber creates repeat rotation; the asymmetrically constructed chambers are configured in such a way as to ensure that the imbalance occurs on alternate sides of the vertical plane at each rotation to produce consistent 180-degree or near 180-degree oscillation about said bearing points that permit 360-degrees of freedom for rotation.
