similar to a 'gravity bong' (but without water) an ironlung is a 2 liter POP bottle that has its bottom cut off. there is a thick plastic bag (shake n' bake bag?) TaPeD around the bottom of the bottle. you cut a hole in the top of the Cap and put a Bowl in there. push the plastic up, inhale to remove air, put the bowl/cap on the bottle, fill it with weed, light it and pull on the String or something that you have TaPeD to the baG. WoW look at all that THICK YELLOW POT SMOKE :D remove cap and inhale. be carefull ive seen people barf off of the high they get from smoking weed this way :D
wtF is an ironlung ? besides hotknives or a vaporizer is it the best way to smoke BC BUD (the crack cocaine of marijuana) ? yep. :D

when you chop the bottom off a 2L pop bottle and take an empty bread bag and tape it over the hole so you can form a pocket. to use you would first make a bowl out of tinfoil and poke holes in it and stick ure weed in it then when prepared push the bag inside of the bottle with yo hand and spark the bowl and slowly pull the bag out of the bottle watching closely that it fills with smoke and remove the bowl and place mouth over drinking end and suck all the smoke out that has been sucked in very fast.
Man those iron lung hoots we took earlier set me on my fuckin ass man
