Does anyone else remember an old educational physics film with a flying bicycle wheel? Answered
I once saw a physics film covering various aspects of motion and the mathematics thereof. In the part about rotational forces, a bicycle wheel (no tire) was spun fast enough to actually take off under precession force. It was very a short flight in an arcing trajectory ending in the wheel inverting its axis and slamming into the ground...hard. I've been wracking my brain trying to remember the name of the film to no avail.
