If you want an easy way to mount the nail and the bottle its as simple as a screw and a peice of PVC pipe. Go to the hardware store get some electrical PVC piping, cut a peice that fits about 2 inches up the bottle, secure this a couple small blocks, I find that three in a triangle works best around it, screw it in pleace. And a screw through the top. Paint the box up brown and if you really want to hide it the way you would a real mine, dig down and get the lid to ground level. About 20 lbs would set this off if dropped a foot off of it. Someone stepping on it would set it off easily. Crawling, may have a chance to see it... disarm it easily and place it where they want it
