Engineered to provide a low-friction rotating surface for experiments involving the conservation of angular momentum and rotational kinetic energy. Its low-friction, ball-bearing design ensures good results. It can be set on a level floor for standing or placed on a stool for sitting. This platform can support up to 200 pounds and has non-skid patches to prevent skidding or slipping. Many other demonstrations involving rotational motion can also utilize this versatile turntable.
