The yellow balls are 7 in a foot, almost exactly. 12/7=1.7SOMETHING

The green balls are bigger. 7 of them measure 12 3/8". 12.375/7=1.77

All of the green-ball-compatible blasters WILL fire yellow balls too... but not as well.

The Buzzsaw's (2006) retaining nub fails to retain yellow balls; they fall right out if you turn it upside down. The Reactor (2003) just lacks oomph with yellow balls.

The electric Ballzooka (OddzOn 2000) will fire the green balls, but makes a loud THUNK sound when it does, like it's passing gallstones and it isn't comfortable doing so.

Green balls do NOT want to go into the Ball Blaster (Larami 1999) or Pulsator (1998).

I don't have a pump Ballzooka (1994) but it came with yellow balls and is consistent with the timeline.

Green balls are bigger and newer.
