Double Cone - Small
Purpose
To demonstrate a center of mass paradox.
Equipment
Double cone on rails, as photographed.
Images
Description
When the double cone is placed on the narrow end of the V-shaped rails it rolls to the wide end. The double cone appears to be rolling uphill, but in reality the center of mass is moving down.
