Simply... the valve is a one way valve that lets in air one way but does not let air out. It it basically a hole with a flap on the inside. The flap closes when pressure is pushing out but opens when pressure is pushing in.. like when you put in the pump nozzle.
At Loch Ness, click the left side of the truck, then click and hold the valve stem (arrow) until enough air escapes.
I think it is like 4-6 pounds or something :)
Buy a new basketball.
The air in a basketball lets the basketball bounce.
You can try using a straw to inflate the basketball by inserting it into the air valve and blowing air through the straw. Another option is to attach the air valve of the basketball to a hair dryer on cool setting to inflate it. Be cautious not to overinflate the basketball to prevent damage.
if you are asking about the air valve on the tire to add/let out air then it is a schrader valve or an American valve
Hold the valve stem until enough air has gotten out of the tire.

A Schrader valve is a type of valve commonly used in car tires and bicycle tires to allow for inflation and deflation of the tire. It is designed to hold air pressure in the tire and can be easily accessed for adding or releasing air using a pump or pressure gauge.
At Loch Ness, click the left side of the truck, then click and hold the valve stem (arrow) until enough air escapes.
The shocks have a air valve just like a tire valve, just take the cap off the valve and depress the insert in the valve to let air out.
a basketball is kinda like a ballon if it has to much air it pops
