I made this a couple of years ago. I probably won't post an instructable, although i might.. It shoots bamboo skewers (pretty fast). Although it doesn't work like a real crossbow (it uses a rubber band), it can still shoot pretty well. Thin bamboo skewers work best(and hurt the most). The thin ones shoot so fast that they can actually penetrate my wall(i won't post a proof picture of this, because i don't want any more small holes in my wall). -It can shoot about 40-45 feet depending on which kind of bamboo skewer it's shooting.
