In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt like.

I'm not heavy, I'm just not spinning at 5000 rpm.

Thats why Thor always spun his hammer before he rode on it.

This is the first Veritasium clip that I saw and its one of my favorite videos on youtube. I still come back to it, not only for the coolness of the science but because it's so well made with narration. talking and music to capture attention.

As children, those of us who are "of a certain age" remember having a small gyroscope. Watching it balance on a string, handling it as the wheel spun to its heart's content, fascinated by the toy. Other than a microscope set, the gyroscope was my favorite...very fond memories!

Plot twist: he's actually the world's strongest bodybuilder

If you tried this before 1687. it woud be soo easy becouse Isac Newton didn't discover gravity before 1687.

I started watching your videos around 7 years ago when I was still in high school, and yet when I see them again today, they still make me happy and amazed!
No doubt you're one of the finest youtubers ✨ -
Just beautiful! Watched these long back, but now I have a new found appreciation for these now that I'm in class 12

Anti gravity cars are possible! All you need is a grandpa with a drill.

Gravity : No one can win against me.
Torque : Hold my wheel. -
The gyroscope does not get lighter when it is is spinning. It just feels lighter. When it is not spinning, and lifted by one hand near the wheel end, two forces are needed to lift it, one each side of the hand, both larger than the weight of the wheel and in opposite directions. That is needed to balance both the weight and the torque exerted on the hand.

Beautiful video Derek!!!

“You may recognize this as gyroscopic procession”
Ahh yes, gyroseptic precession -
Isn’t it obvious? Literally at the beginning it states he’s in Australia

we had a bicycle wheel in a set of forks and spun it with a power drill and that was fun, light but spinning very fast, it was impossible to move it against its wanted direction, felt like our arms would snap before it went against its self, hope that makes sense to you, try it, front forks, wheel in them then spin them up with a power drill, and hold the steering stem with one hand, we did long before cordless drills, new drills might spin faster now, we attached a rubber polishing pad into the chuck and ran it against the tyre,

the effect of this roation is amazing, I picture counter rotating 2 of them might be interesting, almost could be used to create artificial drag in a spacecraft.
-
I want to get this spinning as fast as possible for the experiment
proceeds to talk for 10 seconds after they take power off the wheel -

La inercia para arriba le puede quitar en teoría la mitad del peso.
En otras palabras, la tracción de la masa puede contrarrestar algo de la atracción gravitatoria -
Love to see you do this while floating in a small boat. love to see how the gravitational waves react on the boat..
