Make a lung.
To do this. cut a 2L pop bottle in half.
tape a bread bag to the bottom of the top piece.
Make sure its airtight.
suck all the air out of the bag.
pull it down. squeeze the bottom of the bag.
tape around it. this will be what you pull the bag with.
take the pop cap. carve a hole in the center.
stick some tin foil inside the hole and fold the rest around the cap.
tape the excess tin foil to the side of the cap.
Poke about 5 holes carefully into the tin foil.
fill your bowl. Screw on the cap.
Put the lung between your knees and pull from underneath.
Make sure you burn the bowl to about 75% and then stop w/ lighter.
keep pulling. If you can handle it. Pull it full. Do up about 5-10 of those.
You'll be ripped out of your tree.
Cant go wrong. Best thing to smoke from when you start
