Have you ever smoked bottle?
Cut the bottom off a 2l water bottle
Make a joint
Place alu foil over the drinking hole in the bottle and insert the joint filter through the alu foil.
Put the bottle bottom down into a bucket of water, so the water is right below the filter of the joint
Light the joint
Pull up the bottle = 2l of weed smoke in the bottle.
remove the alu foil and inhale it all.
