You must be referring to a demo that I'm not familiar with. Could you
describe it in more detail? Does the ball actually obtain a net
momentum change, or does it only lurch forward, then backward again.

As normally constituted, the big balls in coffee table Newton's Balls
demonstrations bounce to and fro.
If one chooses a suitably light suspension string for the last ball,
one can arrange for it to pop off and roll away.

I think we are into "DC" vs "AC" momentum here :-)
