Step 1: Ingredients & Tools
-Two spent shotgun shells (if you don't have a shotgun, you can always pick up ones left by shooters at a hide, or just wherever they frequent) (You could try a live cartridge if you really want. ;-) (I've dissected about 3, or 4 which shooters have dropped))
-Knife, or scissors
Step 2: Cut 'em up!
