We have. I made a 2-liter bottle lung with a newspaper bag, scotch tape and tin foil. Also, I created a smoke filter using a 1 gallon orange juice jug, Bounce dryer refreshers, lots of tape and a knife. Genious! Genious! Genious! Spoofie! Spoofie! Spoofie!
your saying the smoke passes through the dryer sheets before you inhale it? I wouldn't do that if I were you, its not good to inhale laundry detergant...
Lungs are awesome, but for mine i just carved a hole into the cover from the 2litre and stuck a bowl in there. never smoke with tin foil.
