i can't believe more people on here haven't used or made lungers, i found that a 2 litre bottle with a bread bag works best and instead of making a bowl in the cap or whatever i took my pipe ( a smaller one ) and wrapped its chamber in electrical tape until it fit snug and air tight in the opening of the bottle and then you can just pack a bowl in your pipe and it makes it easier to light the bowl, also use a torch lighter or butaner lighter to light your bowl because it gets the bowl cherried much quicker than a bic lighter, just be careful not to torch the weed too fast
