GV, Pretty good teams, two-man
As Ref, I check the ball after I check the book (10 minutes). Last night as Ump, I check the ball at 1 minute. No air. Show Ref. Check six at the home bench, all the same. Use the best of seven. 1/2-way through the 1st, during a dead ball, I ask the AD to please find a pump, or a ball with more air, because both teams are obviously struggling with dribbles and misjudging rebounds and bounces. AD took care of it. At the quarter we have three from which to choose. The first one is fine. We gave the ball to both point guards and told each coach of the change. Of course this should not happen, but what procedure would you follow if the air-less ball happened to start the game. Thanks mick |

Other than asking the AD to find a pump as soon as you realize there's a problem, I don't know that you could have done anything better. I had a game this year where, if I dropped the best available ball from as high as I can reach, it wouldn't bounce higher than my knees. There was no pump available at the school. The game was really ugly because everyone had trouble dribbling. Delaying the game while someone left the school to get another ball or a pump wasn't a good option.

2 girls varsity teams and nobody had a good ball?? Don't waste your money on lottery tickets that night. I know it can happen sometimes in a youth game because both coaches leave their ball bag in the trunk of the car and if it's cold outside, the balls lose air.

I/we never checked the Visting team's basketball. We judged that "good enough" would be good enough. ...But it wasn't. mick |

fine with me, it adds a nice twist to the game. kinda like rather than tossing the jump ball, someday i'd like to bounce it toward the corner and let them race for it. or maybe like moving goals.

As the resident physical scientist on the board, I just want to point out that the air is still there - it's just less dense, and takes up less volume.

Hmmmm, if the resident physical scientist were less dense, perhaps he'd exhibit less volume ![]() Ah, yes. The volume of dense physical scientists on the board seems to be rising. Better yet: As the resident smart-dexter on the board, I just want to point out that the physical scientist is still here - he's just as dense but takes up less volume. Yep, just too easy ![]()

If the air is still there the mass stays the same. If the volume decreased: Denisty = mass/volume the Denisty of the ball has increased. I'd be more inclined to say as temperature decreases the air molecules move more slowly, hitting the sides of the ball less often, creating less pressure. But hey, I'm just an 8th grade science teacher.

And when your students get to the 11th grade (?) they'll find out that PV = nRT, which is another way of saying as the air cools (T) or as you let out some air (n) the pressure (P) reduces while the volume (V) remains constant, which it does in this case because the ball is not getting smaller or larger. Just softer. Like our heads. ![]()
