This is a tutorial I made to show you how to make a very powerful and cheap airgun. You may use this design to make as many videos as you like, but please give me credit.
*************UPDATE************************
When you pump this gun up 100 times and fire it, depending on how quickly you pulled the trigger, you would only need to repump the gun 15 times to have it fully charged and ready to fire.
