Do yourself a favor and go grab the bowling ball, stand on a skateboard, and do this demo for yourself.
THEN, take a basketball and do the same thing. See if you go as far in the opposite direction. I got news for you- YOU WON'T. That's because the weight of the bowling ball provides a greater counter-force than the weight of the basketball.
If it were just about "moving air molecules", the basketball would propel you further since it has a greater surface area than the bowling ball. But it DOESN'T. Because it's about equal and opposite forces, not air.
Done.
