Advanced water filtration system (BONG)
made by cutting the bottom off a 3 liter soda bottle and putting a bowl in the screw cap. Used by sinking the bottle with out the cap, up to the neck in a deep, sink, tub or bucket. Then screw on cap with loaded bowl and slowly pull up filling 3 litre with smoke, unscrew cap and place mouth over top and push back down in to the water...Few people can take a full 3 liters of smoke into their lungs at once!
DUDE! That fourth depth charge sank my battle ship! Raise the white flag!
