Spinning toys and tops have unusual behaviors. The famous tippe top flips itself over and spins on its stem. The PhiTOP stands up on its end, which you can also do with a hard-boiled egg. These behaviors all have to do with torque and angular momentum, like a bicycle wheel precessing around a rope due to gyroscopic behavior.
