While going through the garage, I found an old fire extinguisher that had been in there since 1987. It needed to be recharged, but I decided to use it for another purpose. Since I have been working on putting together a military themed motorized bicycle, I decided that I could use this fire extinguisher as a prop. It was the perfect shape for a giant bullet prop that I can carry on the luggage rack.
If you don't have an old fire extinguisher laying around, you can always use one of those aluminum water bottles. I found a couple of the aluminum water bottles at the 99 cents store that would be perfect for a round nose bullet instead of the rifle bullet that this instructable features.
