Hey guys. I have tried many devices to vape shatter and only end up coughing up a headache. Nails, coils, ceramic discs and both ceramic and steel hot plates. I really liked the stuff you can get in vape pens which I researched some to find the main ingredient that makes it work. Polyethylene Glycol (PEG) was used for ecigs till 2013 when they decided propylene glycol (PG) was a better alternative. No idea of who the fuck "they" are..? Anyway, happens that PEG is a "combiner" and can allow oil to be mixed with water. In watching discovery channel when they were in a cosmetics factory, the process became clear. Many cosmetics are a mixture of water and oil based products and here is how they do it. They add, you guessed it, PEG and bring up the temperature to just under boiling. Keeping the product agitated at all times. Keep the heat there for a while and then let it cool slowly again agitating the whole time. The things you will need are: An all glass 20ml (or bigger) syringe. Some Polyethylene Glycol (PEG). A decent atomizer. VG and flavoring are optional. Here's a video I did on the process. Turn the Closed Captioning ON. Click to play YouTube Video The result is something you can vape anywhere and no one will be the wiser. Tastes very nice to boot! Any no more coughing. Have fun!
