Easy way of smoking, empty pop can. Use your thumbs to put a large and even dent in the side of the can. Then take a pen and stab holes in the dent. Easy. However cans are made from aluminum, yet the cans are thick enough that when you hit it it wont heat up enough to release many toxins. So to be on a safER side don't take pro hits, and to be on the SAFE side, use an apple. Just dry the appbowl out with a towel.
