If you are alone, take your time and be patient.

Meth is technically vaporized not smoked, it melts on the hot glass. Everyone hold the lighter right under the meth, and that burns it up faster. Heat the glass to the side of the shard pile, and let the heat spread up the glass to melt the ice instead of scorching it with a lighter. I recommend using a long straw to drop the meth all the way into the bowl and not get it stuck in the stem. You MUST smoke properly or u will burn up your meth and constantly be pissed that you aren't getting high. literally, it just soaks into the pores of the glass. Constant torching makes the glass porous from the reheating and cooling. You can torch it when necessary but always clean it with the q-tip first and leave the meth residue slightly moist so it burns off easier. Make sure you clean your glass piece after every bowl with a q-tip and saliva or water. It was awesome but I was new to smoking and cleaned it with a torch to often which ruined it. DO not use foil, wastes your dope and the aluminum is horrible, far worse than the dope for you. Then keep torching till the hole smooths out.

Once you have your round bubble end, heat one point with the torch grazing the edge horizontally above the bubble when it is red hot keep the fire to the spot and blow until the hole pops. Blow into the end, not hard enough to pop it but with enough strength for it to expand into a bubble. A glass cigar tube heated till glowing red from a torch.
