Spin a box, rod, disc, or asymmetric "book" shape in 3D and watch torque-free rotation do genuinely strange things. The star feature is the tennis racket theorem: spin the asymmetric shape about its intermediate axis and watch stable-looking rotation spontaneously tumble into chaos, a real and famously counterintuitive result. A fixed angular-momentum arrow stays still in space while the object wobbles around it, making the physics visually obvious.
Rigid Body Rotation is an interactive learning tool on VTC. Spin a box, rod, disc, or asymmetric "book" shape in 3D and watch torque-free rotation do genuinely strange things.

A fixed angular-momentum arrow stays still in space while the object wobbles around it, making the physics visually obvious. It runs in your web browser and is free to use, and suits students, teachers and self-learners.
