Response to What would that be equivilant to?

..rifling which made one turn in 12 inches, the rpm would be 48000.

A conventional Dremel moto Tool has a shaft rotation of around 35000rpm.

But a question to the scientifically minded.
We say that a spun pellet may go into precession and nutation while traversing the air at high speed.

To illustrate precession and nutation, we are often directed to observe the gyrating antics of a childs top as it spins about it's axis.

So the question is, would the childs top go into the precession and nutation mode if the top were perfectly ballanced mass-wise and axis-wise?
