[illusion] Anti-Gravity Double Cone papercraft
The mechanical paradox is an apparatus for studying physical paradoxes. It consists of a trapezoidal veneered wooden frame with two brass rails, and a pair of brass cones joined at their bases by a wooden disk which rests on the rails. When the double cone is placed at the low end of the frame, it automatically starts to roll upward, giving the impression of escaping the universal law of the gravitational force.
