I meant to add this:
Don't worry about having to order liquid from anyone with your order. If you go
buy a bottle of pharm grade glycerin and some distilled water, you can literally just put a little bit of the distilled water into the glycerin and shake it up and use it. It won't have much of a taste, slightly sweet, but you will get clouds of vapor and feel like you are smoking.
Then, you can later experiment with flavor by ordering from FlavourArt by pouring out your bottle of "plain" into some tiny bottles (which you can order from FlavourArt) and adding a few drops into each.
