Sir your practical experiments are very interesting and informative ✨✨

If we change the direction of wheel the direction of moving chair also changes because the direction of Angular momentum and Angular velocity is same after changing direction the direction of angular velocity changes and hence changed the direction of angular momentum from upward to downward and also initially the angular momentum in vertical axis is 0 so final will also be zero so chair starts to move in the opposite direction.

Since the angular velocity vector direction changes the direction of rotation of man changes

Sir if you spin a T shaped body it will change its direction periodically
