There are several ways to let air out of a basketball. The most common method is to use an inflation needle, inserting it into the basketball's valve to quickly deflate it. Alternatively, a ball air pressure gauge can be used by inserting it into the valve and pressing the air release button. If you don't have access to these tools, a paper clip, bobby pin, or empty pen chamber can be used by poking them into the valve to release air. Another method is to use a straw by cutting a small notch in it, creating a tight seal around the valve stem, and slowly releasing the air. For those with a ball pump, the pump can be connected to the valve stem and switched to deflate mode, sucking the air out of the basketball.

What You'll Learn
Using an inflation needle
To let air out of a basketball using an inflation needle, you will need a basketball pump with a needle attachment and a pressure gauge. Basketball pumps are readily available at sporting goods stores and online. You can also use a bike pump with the proper needle.
First, locate the valve of the basketball, which sits near the bottom of the ball. This is where you would typically insert a needle to inflate it. Insert the needle into the valve and ensure it fits snugly to prevent air leaks.
Next, connect the pump to the needle. Before beginning the deflation process, locate the lever or switch on the pump that allows you to switch between inflation and deflation modes, and flip it to the deflate position. This will reverse the airflow, causing air to be released from the basketball instead of pumped in.
Once the pump is securely connected and set to the deflate mode, you can start deflating the basketball by pumping the handle. Keep an eye on the pressure gauge to avoid under-deflating the ball. When the desired pressure is reached, carefully remove the needle from the valve.
Finally, securely close the valve of the basketball to prevent air leakage. Some basketballs have a built-in cap or valve cover for this purpose.

Using a ball air pressure gauge
First, lubricate the tip of the pressure gauge with water or glycerin. This will make it easier to insert the gauge, prevent valve damage, and reduce the risk of air leaks. Next, insert the pressure gauge into the basketball's valve. The valve is usually located near the bottom of the ball or the inflation hole.
Once the pressure gauge is inserted, it will display the current air pressure reading. The recommended air pressure for basketballs typically ranges between 7.5 to 8.5 pounds per square inch (PSI). However, it's important to check the manufacturer's guidelines, as the recommended pressure may vary depending on the organisation and level of play. For example, the official game ball in the NBA has a recommended air pressure of 7.5 to 8.5 PSI, while women's basketball in the NCAA and FIBA recommend a slightly lower range of 6.5 to 8.5 PSI.
If the pressure is too high, you can release air by pressing the air release button on the pressure gauge. This button is usually located on the side of the gauge. Push and hold the button down to release air until the pressure reaches the desired level.
Once you've achieved the correct pressure, remove the gauge from the valve. It's a good idea to periodically check and adjust the air pressure in your basketball to ensure optimal performance and longevity.

Using a ballpoint pen
To let the air out of a basketball using a ballpoint pen, you will need to take the pen apart. First, remove the ink chamber from the pen and take off the nib. You may want to wash out the ink chamber, or you could snip off a portion of the chamber that doesn't contain any ink. Gel pens are not recommended for this task, as they have thicker chambers.
Once you have the empty ink chamber, lubricate it with water. This will help it slide into the basketball's valve more easily. The valve is located near the bottom of the ball. Gently push the lubricated ink chamber into the valve. You should hear a hissing sound as the air escapes from the ball.
If you only need to reduce the pressure a little, it will only take a couple of seconds. However, if you need to let out more air, leave the ink chamber in the valve for longer. You can speed up the process by squeezing the ball gently, but be careful not to apply too much pressure, as this could damage the ball.
To check if you have released enough air, perform a bounce test. Hold the basketball so that it is level with the top of your head, then drop it. If the ball bounces up to your elbow, it is correctly inflated. If it bounces higher than your elbow, you will need to release more air. If it bounces lower than your elbow, you have let out too much air, and you will need to inflate the ball again.

Using a straw
Deflating a basketball using a straw is a simple process, but it may take some time and effort. Firstly, you need to cut a small notch at the end of the straw. This notch should be large enough to fit over the basketball's valve stem, but small enough that the seal is tight. You can use scissors or a knife for this. Once the notch is cut, place the straw over the valve stem and press it firmly to create a tight seal. This prevents air from escaping through the sides of the straw.
With the straw securely attached, you can begin to slowly release the air from the basketball. Gently press down on the ball to let the air out in a controlled manner. Be careful not to apply too much pressure, as this could cause the straw to come loose. It is important to be patient and keep applying pressure until you achieve the desired level of deflation.

Using a ball pump in reverse
If you have overinflated your basketball and need to release some air, but can't find the inflation needle, you can use a ball pump in reverse to deflate it. This is a quick and easy solution to get you back in the game.
Firstly, locate the valve stem on your basketball. This is the small, rubber piece where you would usually insert the needle to inflate the ball. You will be inserting the nozzle of the pump into this valve to deflate it. Ensure that the nozzle is securely attached to the valve stem.
Next, locate the switch or lever on your pump that allows you to alternate between inflation and deflation modes. Flip this switch to the deflate position. This will reverse the airflow, so instead of pumping air into the ball, it will now suck air out. Make sure the switch is securely in the deflate position.
Now that you have securely attached the pump and set it to deflate, it will begin to remove air from the ball. You can monitor the pressure levels with a pressure gauge or by pressing down on the basketball to check its firmness. Release the air in small increments, checking the pressure periodically to avoid deflating it too much or too quickly.
Once you are happy with the pressure, remove the pump from the valve stem and your basketball is ready for action.
