The gauge on your pump, if you have one.
About 8 PSI
pressure would always change due to temp, so u gotta take that into account.
7.5 to 8.5 psi
A concrete strength of 3500 PSI should be just right for a basketball court.
The layer of crap on the sand is getting thicker. Wait until the manufacturer's upper limit of 120 PSI has been reached, and watch that baby explode.
Assuming standard atmospheric pressure of 14.7 psi, the pressure difference in the basketball is 5.3 psi. To estimate the volume of air in the basketball, you'd need the basketball's size, as well as assumptions about temperature and ideal gas behavior. This volume would be significantly larger in standard conditions than when pressurized.
I pumped up a basketball to 60 PSI, at about 55 it started making crackling noises, when I got to 60 PSI the crackling noise was constant and within 2 seconds of reaching 60 PSI the ball exploded. The ball was a Wilson Optima Rubber Basketball .
you become president...and make pink illegal. that would make Paris Hilton explode
No
if you give an aspirin to a bird eventually it will explode:)
Dropping Mentos into soda will cause it to explode.
