make one out of an apple.... its easy and not as sketchy for somebody your age b/c you can just ditch it when your done.... Ill tell ya how to do it...
1st pull out the stem of the apple and take a pen (or something similar in diameter).. and poke a hole down through the center of the apple but dont go all the way through...
2nd take your pen and go through on the side of the apple and make sure it hits the same channel you made with the first one ok... you can suck on it to make sure the air is flowing freely....
3rd do the same thing for a carb above the mouth peice and close the the top of the apple.... make sure that that hole goes through the first hole too.... make sure that its pulling air through too..... DO NOT poke any of your holes through the opposite side of the apple....
4th pack your bowl at the top of the apple and enjoy!!!!!
