Bike Wheel Experiment: Angular Momentum

What can a bike wheel teach us about rotational inertia? In this educational video, Museum Educator Jeannine stands on a turntable while applying force to a spinning bike wheel. Because the bike wheel has a high spin rate, it also has a lot of rotational inertia. This causes the bike wheel to push back against Jeannine, causing her to spin in the opposite direction on the turntable. This exciting science experiment is a great example of the conservation of angular momentum!
