Center of Mass, Double Cone, and Plane Demonstration, Each

Details

Here is the corrected text: Easy to use - simply place the roller cone at the bottom of the ramp, let go, and watch it roll up and sit in the grooves. This apparatus consists of an inclined A-shaped ramp with a double-ended cone roller. Made from durable wood and clear-coated for decades of use. Fully assembled, this product requires no assembly. Designed for physics classrooms, it also makes a great executive gift or desk ornament. This ingenious device is perfect for physics demonstrations, executive gifts, or desk toys. Place the double cone roller at the bottom of the inclined plane and watch it travel "up" the ramp with no applied force. The physics behind this demonstration is that as the roller moves up the ramp, its center of mass actually moves downward, driving the roller up the ramp itself. Amaze your students and colleagues with this remarkable device. Constructed from durable wood and clear-coated for decades of use, it measures 17"L x 5"W x 2"H.
