Ultra-high-speed rotation. Customary among us.

A few days ago. I have replaced the crankshaft bearings for powered paraglider.

Bearing that was removed is made ​​to do the ultra-high-speed rotation prior to disposal.

It has become customary among us.

This runaway was stopped on the vegetable garden.

At that time, I felt the gyroscopic effect in the hand.

If I did it using the larger bearing, what happens?

For example, differential side bearing of the car, bearing of the turbine of the hydroelectric power plant.

Will it go willingly while destroying the house?

I think if that was the case, that it can use in one episode of Sakigake !! Otokojuku.
