Picture this: a testube, a two hole stopper, a piece of glass extending from one hole to near the bottom of the tube, and a short piece of glass in the other hole, just long enough to use to hold a vinyl hose about six inches long.
Remover stopper. Insert meth in bottom of test tube. Reinsert stopper. Apply heat until meth begins to vaporize. Inhale slowly.
Yes, its that simple.
