Method
There is no particular secret to this illusion: the performer simply holds out one hand sideways with the palm out and the tip of the thumb folded down behind the hand. Then, they place their other thumb bent so that the tip appears to be connected to the folded-down thumb with the forefinger bent to cover the joint.[1]
