Optimizing Spinning Tops

Spinning tops are a common child's toy, but much more principles of physics are at play than meets the eye. Moment of inertia, stem circumference, weight, friction, and acceleration all play their part.
Does weight affect the speed of a top? Do wider tops spin longer? Do heavier tops spin longer? Find out!
