another reason to precess upwards |

Again this is not my video.
Because the bearings are garbage, the spin is given to the frame, and because of the slower rate of precession needed for the larger-diameter gyro mass of the frame pivoting at the same radius, the larger-diameter gyro is effectively being pushed in the direction of precession, and rises up. |

| | | At the end he picks up the gyroscope to process again at the slower RPM and here you see a point I made a long time ago that gyroscopes want to precess around the center of mass and not really precess around one end.
That fact is what makes it look like it's driving in a specific direction, like Laithwaite's large suspended from the ceiling gyroscope.
- this of course applies to a normal force at one end so a torque can be applied at the other end as this does not work in space as there is no torque, just a push at one end and the other end is not prevent it from moving in the same direction of that force.
