Hold the ball up to your face and slowly let it drop. If the bottom of the ball bounces up past your waist or slightly higher, then it is fully pumped. If the basketball bounces up close to the chest, it means it has too much air. If it does not bounce up to the waist, it means there is not enough air.
How do you know if your basketball has enough air?
A quick way to check if your ball has the proper air pressure is by taking this simple test. Drop your basketball from the height of your shoulder and leave it to bounce.

Why would a basketball explode?
A Basketball Can Explode If It Gets Too Cold
This is because of how gas molecules react in the cold. When a basketball is left out in the cold, gas molecules contract and, as such, will have less energy and move more slowly. This leads to the basketball having lower air pressure, which leads to the ball bouncing lower.
