Well, they just showed you how to make it... I remember some friend's and I made a bong like that once.
That music was annoying as fuck. i think if i saw that guy I would not hesitate to punch him. As for the gun, it's a water gun usually used in pools and shit.
Haha, that was entertaining! Although that volume of smoke seems like it would induce a rather uncomfortable high.
I don't know if you guys are missing the point, it's not the actual smoking device itself that is important, just fuckin look at it! It's a waterless bong! you could make smaller ones, too... Maybe a one footer? You guys cannot say that a smaller version wouldn't be useful.
It wouldnt be as useful as a regular bong but would be more lke a ritual, similar to the gravity bong.
I t'ink that the video is self explanatory in regards as to how to make one. The only difficult pieces would be the gun and the bowl head, which should be available at any toys r' us or bong shop respectively. It's really just a variation of an 'lungs' bong. For those who don't know it's when you take a water bottle (pick a size that feels right for you, i've seen pints or 2 liters used, although never a polar jug) cut the bottom half off, get a strong plastic bag (a heavy duty ziplock should do the trick) and tape it to the bottom. You puncture the cap to the bottle, put the bowl in there (like they did in the video) and fill 'er up. you push the bag in as far as you can go, then light the bowl and pull the bag out. The bag creates a vacuum which fills the bottle/bag with smoke when you pull it out, then you take the cap off, put the bottle end over your mouth and push the bag in. I never liked 'em. It's been my experience that whenever you let the smoke sit for more than three seconds it makes it incredibly harsh (that's why there is a carb on bongs).
