Part 5/6:
When I subsequently placed the wheel directly on the warmed bowl, the expected rotation was minimal compared to the more vigorous movement generated by the hands above it.
Hands and Directionality
I changed angles while filming and adjusted the placements of both hands to speed up the wheel's rotation. This adjustment proved impactful, likely confirming the instructions' claim relating to hand positioning.
I never observed activation of the wheel when keeping my hands flat on a sturdy surface; however, re-engaging with my left hand created additional motion. Interestingly, holding my right hand with my left prevented any rotation until I released the right hand back to its position.
