If you know someone at an auto repair shop or a tractor repair shop, see if you can use the air hose with full pressure. You just need to use a blowgun with a rubber tip. Remove the nipple and press the rubber tip into the threads. Point the muzzle in a safe direction and hit the lever full down. You may or may not find the jag after it flies out. Mine put a dent in an aluminum door on the far side of the shop. No joke.
