Double Cone, Cylinder and Plane

PIRA 1J11.50

Description:

A cylinder will roll down the inclined plane (created by the two "v" shaped tracks), as expected. However, the double cone will roll up! Actually, this is an optical illusion; the double cone shape allows center of mass to roll downhill since the two arms get wider as the incline increases.
