The comments are very spirited and the maker of the video is quick to reply.
One commenter says:
It’s not really anti gravity. He’s just eliminating the lever force multiplication of the weight through the gyroscopic effect, shifting the effective centre of mass.
Here is wikipedia‘s articulation of the effect:
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.
In astronomy, “precession” refers to any of several slow changes in an astronomical body’s rotational or orbital parameters, and especially to Earth’s precession of the equinoxes
We hope you enjoy the video and only experiement with the supervision of a professional.
Pretty cool experiment! Makes sense.
Match the vibrational spin of the object to the axiomatic spin of Earth – the object would spin under its own power and levitate.
It’s not trippy..it’s science
wonder if force of impact is greater if to swing and hit with spinning, oppose to non spinning
Polarized mercury and a centrifuge
trippy if you are retarded and don’t understand gyroscopes…this has been a carnival trick for like a hundred years
It’s a time thing
Did that yrs ago
Now, lift it by the same end you did before it was spinning. It’s still 19kg.
Angular momentum is not anti-gravity
mind bending

I always wondered about throwing weights. Like the heads of an engine around a spindle on a bearing being timed and rotating in unison then “throwing” more weight up at a calculated time causing the object to lift. In my head it seems like doing this at the right times with enough weight in a consistent pattern could cause the object to travel upward. Seems like someone could accomplish this easy nowadays.
If the gyro procession creates a “lift” effect, then I would surmise the weight on the scale while the wheel is spinning would be less than his body weight plus the wheel not spinning.
