In the Double Cone and Ramp Demonstration for physical science and physics, be amazed as the cone in this demonstration appears to magically roll uphill.
Can something roll uphill? Students will be amazed as the cone in this demonstration appears to magically roll uphill. Careful inspection will reveal that the apparent gravity-defying paradox is really not what it appears to be. The center of gravity of the cone is actually so low that it is actually rolling downward when it appears to be upward.
