This model (a wooden version) was used in one of the physics experiments described in the works by the French abbot Jean Antoine Nollet (1700-1770).
When the double cone is placed at the lower end of the frame, it automatically starts to roll upward, giving the impression of defying the universal law of gravitational force. Because of this phenomenon, astonishing in its seeming contradiction of common sense, the apparatus was often described as a “mechanical paradox.” [for more information, visit http://www.museogalileo.it/]

Quando il doppio cono è posto sul bordo basso del binario, automaticamente comincia a rotolare verso il bordo alto, dando l’impressione di non seguire la legge universale della gravità. A causa di questo strabiliante comportamento, che sembra in contraddizione con il senso comune, l’apparato fu spesso descritto come un “paradosso meccanico”.
