At 1:35 after he has already explained the right hand trick, he then explains it again BUT he's mistakenly spun the wheel clockwise for the demonstration but says it's spinning anti-clockwise. In the final shot of him on the pedestal he's spun in the correct way but actually has a different wheel without the white marker. So the mistakes are several.

Thanks a lot, Will Smith!

All other demonstrations I have found on this topic show that when the direction of torque is reversed by a change in direction of spin, the person rotates in the opposite direction, not stopping as in this demonstration.  It seems viable that the system should stop for a moment as the change in direction of the force could result in a moment of zero velocity until time and force in the new direction results in a new net force and momentum.

The error in this video is at the last demonstration when he says the wheel has an angular momentum of positive L , actually it is negative L ( if u observe the wheel close ly) and so when he flips it ,the system rotates with an angular momentum of -2L.

@sarthaksharma9322

when you spin for the first time same thing happens right?

@rommel23nb

great video-- I will try it with my class

@vinayseth1114

Is this a standard pedagogical tool used in the US- Because the recommended videos section is showing me a lot of videos on other physics-related channels with the same demonstration- is this demonstration also used in American schools to clarify the concept?

@popayed

What makes l to l,not -l. How does wheel know it is turning right or left.? And if you take wheel when it is upside down,i mean -l does it act like l?

@tusharkantdeo

Make a video on MOTIONAL EMF AND its real life application.............plssssssssss

@adosar5414

when you are in the ground angular momentun is conserved?

@markandrews1219

Lecture 24: Rolling Motion, Gyroscopes l 8.01 Classical Mechanics, Fall 1999 (Walter Lewin) watch from the 23rd minute if you want to fast track to the same demonstration. Totally different outcome....
