Sorry to tangent, but WHY ON EARTH would you pay $2,800 for a 15 foot soccerball!?!

I've saved for it since I was 5.

My idea was to use it as a house.

Which could roll around like a hamster wheel.

On Mars.

A mental vision of that is disturbing.

They don't have any with the official FIRST logo on them, but you can get a same size/weight ball with a tennis ball/magic 8 ball/etc. cover instead, and they are cheaper that way. Or, if you already ordered some extra balls from AndyMark and those popped, you can keep the cover and just order new bladders from Sportogo.

Or you can buy the official FRC Ball directly from SPORTOGO. I believe the part number is SP-014ROBOT. I placed an order for two of the "25in Volleyballs" (one red and one blue), and received an email asking if I was part of an FRC team and that I could switch my order to the official balls. I don't think the balls are listed on their site, but give them an email or call.

The balls are still $52ea.

Our ball has 2 leaks. Has anyone used a inner tube patch kit. I worry that the solvent will melt the foam material. We are currently using a bladder from 5 below until we get our replacements.

I'd recommend just using an exercise ball and ordering a new one tbh, we had no luck successfully patching ours, the tear just continued to get bigger.

Could you say what RPM you were using when the ball popped so those of us who have yet to pop ours know what is "too fast"?

I'd rather have a smiley face ball personally.

It's not simply RPM. It's compression, wheel diameter, tread material, number of wheels, wheel placement (angle of contact with ball), ball inflation, random factors (hit the seam or the zipper the wrong way), etc etc etc.

Well, here's a photo of one of our prototype shooter wheels, and we did eventually pop the ball. But we repaired it (the ball) with a bicycle patch kit.

Thanks Don. You made my day.

The real question is, did it improve grip?

Very funny. Do you really expect us to believe that?

That you used a bicycle patch kit.

Don, do you have any numbers on the coefficient of friction between your wheel and the ball?

coefficient of friction: 1.000000.....1
Yup, broke physics
