Portable Grenade Launcher by the Jolly Roger

If you have a bow, this one is for you. Remove the ferrule from an

aluminum arrow, and fill the arrow with black powder (I use grade

FFFF, it burns easy)and then glue a shotshell primer into the hole

left where the ferrule went. Next, glue a BB on the primer, and you

are ready to go! Make sure no one is nearby.... Little shreds of

aluminum go all over the place!!
