Ball soars from one hand to the other with out a force to keep it moving. The hands are flat and only moving when the weight of the ball has pushed the hands down, just as if it was a spring under a stair only rising when the foot lifts, and not forcing the foot up and off.
The question remains, do we know the force at work?
It seems it may be a similar force to that of a heat wave in the sebse that you cant see heat waves unless at the right angle, but otherwise they are unseen. Yet could indeed be felt if you were to put your hand abobe them.
So invisible but still powerful.
