yeah, that's itEven a good link will do.
Find a new bottleUse an ink pen and poke a hole in the side of the bottleInsert a drinking straw into the hole (it should fit snugly)Remove the cap and make a bowl out of tin foil over the openingPoke tiny holes in the foil, carefully, with a pinPlace bud in bowl, light it, and inhale the smoke through the straw.
You need a carbPoke another hole in the bottle 180 degrees from the other holeput your finger over the other hole while your hitting it and then release your finger to suck the smoke outAnd if you need it air tight, throw some tape around the base of the foil.
In between the trash man and the remanufacturer, the metal (mostly cans, but screen doors, car parts, etc) is shredded and washed, then crush packaged.
