The pool ball cannot spin without angular momentum. Clearly a single axial strike cannot give such angular momentum, and not only did the pool ball has planar angular momentum (turning left and right) it also possesses vertical angular momentum (making it slow down and even roll backwards).

By simple dynamics, this is not physically possible without external forces on the ball other than the single strike. I suspect there are magnets both under the table and in the pool ball. Prove me wrong otherwise.

By simple psychology, if he is so good he should be world champion already.

Conclusion: One or more of the tricks shown is not physically possible without magnets / other means of external forces.
