This demonstration has a couple components. A bicycle wheel is mounted on an aluminum shaft, with copper wire wound around the rim to increase its moment of inertia. There's a modified stool, which has had footrests welded on and sits on a large bearing mounted to a wooden base.
Demonstrate how conservation of angular momentum affects the motion and rotation of objects.
This demonstration has minor hazards in the form of the spinning wheel and the stool. Spinning yourself too fast can lead to loss of balance and injury. The wheel, if spun at a speed, can also be dangerous. The rim of the wheel could scrape skin and getting a finger caught in the spokes would be quite unpleasant. Take the necessary precautions!
