sharp knife
1 plastic soda bottle, 1 or 2 liter
1 long tube the length of the bottle
gum/tape
1 rubber hose at least a foot long
sheet of aluminum foil
Instructions:
Using your knife, place a hole around the round part of the bottle near the top. This is where you will put your rubber house to inhale the smoke. You can put the hole there or around the middle of the bottle as shown in the diagram below, it doesnt really matter as long as it isnt too close to the water. To make the hole simply push the knife against the bottle where you want it and twist it back in forth while pushing in. This is tedious but will make the most evenly shaped hole. After a little bit it will cut through and you can just twist it around to make it as big as you need.
Optional In the middle of the bottle make another hole exactly the same as your first one if you want a shotgun or rush on your hookah. You may not have to do this if your bottle is small enough. The purpose of the shotgun is to clear all the smoke out of the chamber once it has been filled by taking your finger off the hole which emptys it into your lungs as you inhale. If you add the shotgun make sure it is covered by your finger with every puff you take untill the end of ur hit, then release it and the smoke will be sucked into your lungs.
Take your long tube and stick it into the top of the bottle. The tube should come all the way down inside the bottle so it almost touches the bottem. Make sure the tube is sticking out of the top at least an inch.
Tear or cut the foil sheet into a 5x5 in. square.
Fold the 5x5 square in half and roll it into a funnel. You may want to try rolling the foil around a sewing needle so you can be sure air will get through. You dont want the hole in the funnel too big or else your green will pull through. Suck from the bottem of the funnel to make sure air gets through fairly well after it's done.
Hold the top of the long tube where it pokes out of the top of the bottle. Stick the foil bowl into the tube and seal it using gum or tape. Dont seal the tube (stem) to the bottle, just make sure the bowl is attached to the stem.
Take the rubber hose and stick it in the first hole you cut near the top of the bong. Seal it with gum or glue.
Take the stem and bowl out of the bottle and fill it with enough water so that when you put the stem and bowl back on it covers the bottem of the stem by an inch or 2.
Stick the stem and foil bowl back into the top of the bottle. Using the gum or glue you can now seal the stem directly to the bottle.
If you have used glue, allow time to dry. Otherwise pack your bowl, stick the hose in your mouth and toke it up.
