Bread Bag Gravity Bong

Materials

-Knife/Exacto Knife
-Plastic Water/Soda Bottle (Size doesn't matter)
-Foil
-Tape
-Safety Pin

Instructions to make it

First, remove the cap of the bottle and cut the bottom off to where there is still about 4 inches left from the mouth piece.

Second, take the bread bag and tape the opening around the bottom of the bottle so that it is air tight. Make sure that this is air tight and secure or you could lose lots of smoke. It would be a good idea to blow into the mouth piece and lightly press on the bag while hold the mouth piece shut to test how air tight it is.

Next, take the foil and mold it into the mouth peice of the bottle so it's pretty snug. You want it to go into the mouth piece just a little. Then poke holes that are close together where it dips into the mouth piece but you don't want to make big holes. (We're going for air tight here, but remember your going to have to remove this at some point) This is going to be your bowl.

Instructions to smoke

First, hold the bottle vertically and push the back into the bottle.

Second, place the tobacco in the bowl.

Then, light the bowl and slowly pull the bag out of the bottle till it is pretty much inflated.

Finally, remove the foil/bowl. Put your mouth on the mouth piece and inhale and push the bag back into the bottle.
