ebay, pharmacies, gardening shop.
can minors buy it too
As long as you give them an innocent reason for buying it, it should be OK.
Mention gunpowder, explosives or rocketry and they won't sell you a gram.
Wherever you find it, be careful with that black power, you hear?
This must be a typo. Sulfur is an ingredient in black powder, amirite?;-P
Haha, yep. Thank you autocorrect. Although like powder, power should also be used responsibly. RIP Uncle Ben.
Yeah, I felt bad for Spiderman's Uncle Ben. It was like he died just to provide a poignant memory. Almost the exact same thing happened to Batman's parents. Very sad.;-PThere must be great power in alcohol too, because people keep telling me I should drink it responsibly.
Might have been right the first time!
Chemists, if you are willing to pay more and/or need pure stuff.
Pretty much any garden shop.
Feed mill or farm supply
