You guys should use all the things wisely. When you empty your CO2 Tank you should buy like 4 packs of the 3 D Sized Model Rocket Engines and take off the card board coating then take them all and crush them in a rag with a hammer. Then funnel your powder into the empty CO2 tank so that it is about 3/5 full and then put your home made or store bought 5 foot fuse ( YES. 5 Feet. ) then light it and run about 30 yards away. Now you can watch the little explosion and hope that you don't get hit by the metal pieces of the CO2 tank.

Back on topic. Ouch that probably hurt, getting hit in the face OWW. I got shot in the eye with 3 air soft pellets from 15 yards and that hurt like hell but PB gun in the face damn.
