Double Cone and Ramp

$14.95 $7.49

An inexpensive and effective version of this classic paradox apparatus. The ramp is 45cm (17.75”) long and 4cm (1.6”) high. Its inclination is 2.5°. The double cone is 16.5cm (6.5”) wide and 8cm (3.1”) in diameter. Because of the angle of the cone, its center of mass is lower at the top of the ramp than at the bottom, so counter-intuitively, when released it will roll up the ramp instead of down.  Instruction manual included.  Ages 7+
