Do hard boiled eggs spin the same length of time or number times as a raw egg?

No, hard boiled eggs spin the same amount of time as a raw egg.

The factors that affect how long an egg spins are its mass and the friction between the egg and the surface it is spinning on. The mass of a hard boiled egg is the same as the mass of a raw egg, and the friction between an egg and a surface is not affected by whether it is hard boiled or not. Therefore, the amount of time it takes for a hard boiled egg to stop spinning is the same amount of time it would take for a raw egg to stop spinning.
