hello, this is very easy to make and is slot of fun. and it's safer than you think. to make this cool lighter gun you will need BBQ lighter and travel size shampoo bottle.
Step 1: WATCH VIDEO!!!
To see video tutorial with step by step instructions, as well as see this powerful be gun in ACTION, I suggest you to watch video first.
Take apart BBQ lighter and get wires and gas pipe out. keep the tube, it will be a barrel later. now make a hole at the top of the lighter like shown, to be able to get wires out and put lighter back together. Once again I suggest you to watch video to see what I'm talking about. Also secure these to wires closely one to another but not too close, this is gonna be your egnition.
Now take your bottle and poke a hole at the bottom big enough to be able to fit wires and gas pipe in. then attach bottle to the top of your lighter like shown. I used some clear tape since it doesn't have to be too strongly attached. then put wires and pipe into a hole and seal this hole with hot glue.
Now take a cork and poke a hole in it. big enough to fit that netal tube from lighter. also I cut off a piece of that tube to have it perfectly straight inside and out. then put this barrel though a hole. and seal it with hot glue. and it's ready. to load it just place a bb pallet ,or a berry like I did, into a barrel and screw it onto a bottle. then Pres trigger a little bit, but don't click it. hold it for 5 seconds and aim and press trigger all the way till it clicks. BOOM gas explodes inside of the bottle and pallet shoots with incredible force.
