It's tempting to think that people will act rationally but how do you explain this:

The new Rick Roll? Damn...you got me.
It happens all the time on the 8or9 ball break shot with high english, cb bounces back and goes forward. But of course the whole mass deal is ideal for it to happen. Why would the cb in 3c be lighter? i know the balls are bigger than the ones for pocket billiards, to me they would be heavier if anything.
It's relative to the objects that collide. I don't know what the regulation weight is, or if the red is constructed differently than the yellow and white. It could very well be lighter. *shrug*
Being airborne might explain the bounce. There's interaction with a large "immovable" mass, the slate. It seems logical to me, but I have my doubts that the shallow angle would be enough.
All I know for sure is that the shot was staged, due to it being recorded the way it was. The other certainty is that it bounced odd. Only 2 people know for sure, the guy recording and the guy shooting.
