im semi proud of the sheer simplicity of this if you're like me and want a chill smoke in between burning your lungs ideally you get a mcdonalds straw, water bottle, ice ice cold water poke 2 holes one 2/3s down for the straw, one closer to the top which you cover with your thumb as a carb pull out your filter about halfway out bite off/ cut out a bit of the filter so its kinda cone shaped at the end so it can fit snugly into the straw after the filter is in there nicely slide the cig back down and the paper should enclose the outside of the end of the straw and youll feel it nicely bump back against the filter and viola! mouth on the top, cover the carb, light the cig and inhale a little harder than you would normally, you should see the top of the bottle get white with smoke, release your thumb and there you are! :) honest to god my lungs feel butter already and this is pretty easy to assemble when you are craving
