To launch a rocket you simply need proper Aerodynamics to keep the bitch from flipping mid air, a large amount of thrust and a nice solid multi stage booster system to lift you out of Earths atmosphere in a few minutes. 3 Stages and some simple math to calculate the Delta V and orbit. Humans were literally launching shit into orbit before anyone ever got high on meth.https://en.wikipedia.org/wiki/Orbital_inclination_change
To "smoke meth" which is actually vaporizing it in a glass bubble pipe you first need to inspect your fuel source (the tek)
A proper hit is best achieved by knowing every property of the crystal you are about to melt, it helps to know its purity%,how it was made, if it's a sulfate or hcl salt, even the structural isomer is important to know, this affects the melting point and can throw it off by a lot.
Also there is much debate into what to use to melt/smoke the shit. Candles are only good for melting the stuff in stems but should never touch the bubble, soot is not good for the pipe even though you can just wipe it off if you do get soot somehow the pipe might need to be cashed (outside) cleaned with hot acetone or possibly even discarded.
Pipes are easily ruined from burnt shit, contaminants, dust, hair. If you use any marijuana paraphanalia on a tek pipe it crates a horrible mess and ruins the pipe, even one pin head sized glob of resin can render the finest glass dick useless. Stems should also be taken care of and lot allowed to get totally fucked up like this girl has!
How you load the shit is also important, do not ever touch the shit unless you have gloves on, I use straws to load shit through the carb, never put loose meth down the stem or some might stick to the side and you will suck meth into your mouth which is the worst taste ever.
ALso you should be careful how you hold and tilt the bowl, watch the puddle, don't let shit recrystalize upside down and keep the viewing window clear with periodic cleaning hits or else you will start down a slippery slope or ruining the pipe and have to buy/make so many of them. 1 pipe should last a while but I tend to rotate like 5 at once.
STAGE 1: melt down the rock/rock pile into a puddle, keep the lighter a few inches from the bowl and twirl the pipe around like your rocking a baby or a boat,soon it will start to smoke and turn into liquid, you can start inhaling the vapor lightly like a mild soft kiss but not too hard because right now the puddle is in a very complicated state of matter. Its a liquid but it needs to cool and crystalize, in this form its very sensitive to heat and air movement which is why you should kill the flame and inhale very softly so it can properly cool.
inhaling too much will cause it to spit and spatter around the inside of the bowl and stem instead of melting in one nice pile.
once its melted you can move on to
STAGE 2: Rocks have strange melting temps and require too much heat to properly "smoke" which is why you must melt it into a puddle, let it cool to properly smoke the drug.
All you do now is the same thing with the flame, very slowly melt that sucker down again (it should take way less heat and be more sensitive) move the bowl back and forth it should quickly turn liquid and start smoking a lot, probably more than you can handle so don't keep the heat on too long if you aren't prepared to suck that glass pipe like you owe it money, because good meth is not cheap and wasting it sucks. I don't like to see anything out of the carb, I want it all in my lungs.
I dont know whats better, holding it in or blowing it out while you keep smoking, the hookers I know all blow out between hits and waste so much, burn it, they all suck at smoking. Nobody does it right.
I hold it in as long as I can and inhale a lot, probably lots of CO2 poisoning but oh well, Idk feels good man. Waste not want not. I OD several times a week from smoking alone.
