A few days ago I ordered a 600g of potassium nitrate and it came too late for the 24th of June (the quebecker's 4th of july) so I still have them with no special occasion to light a smokebomb with all of it. I don't know what I should do.

Should I:
1-Order more (5$/100g, no alternatives) until it becomes huge
2-Light all of it right now
3-Light it in small amounts, keep some for later
4-Other, please specify

Uhhhhhhhhh well...first of all you are getting ripped off with that KNO3...

I don't know where you are going to be doing this and luckily you haven't said but I'm going to assume that you are watching out for your safety and others or I won't be able to finish my post.

My advice would be to have several small batches spread over a large area and set off together. It might look cool, whatever floats your boat.

Lighting off a 1 kg charge would probably be a bad idea though.

Well..... The most I have ever done is 5 pounds. It's not a good idea at all. That was one of the more nubish things I have done. You are getting really ripped off on that KNO3 I would buy stump remover it was $2-3 a pound. Also with large ones don't bother melting it, you won't notice the difference and it is not practical.

Also where are you ordering you KNO3 from?

I think arctica did a 20kg smoke bomb once. It was leet.

As retarded as it woudl be... i should probably buy another 50lbs of KNO3 and find alot of sugar, charcoal, wax, etc... and make a really huge smoker...

but no...

Hell no! Too big and you start losing a lot to heat. If anything, spread it out over a larger surface and give it a touch of olive oil if needs be.

OP:
You really should make a bunch of small smokers, so you'll get a hang of making casings/fuzes.

I know, but that's the only available place where I don't raise suspicion. I'll push my search for solid state stump remover, but the results could be deceiving.
I know there's an easy explanation to that, but could you develop so I know we're talking about the same dangers?

I'm gonna light it on an high spot and get the hell out of here after or at least hide somewhere nearby to film the whole thing for youtube. The biggest smoke cloud=the most attention=good. I am planning to light the whole thing (on a spot where it can't light a forest fire) and I just wanted to know if anyone has better ideas...

I know, I never melt it anymore as it smells, it takes time and I have nothing but a BBQ to cook (I learned my lesson for this one ). As mentionned above, I'll search further for stump remover.

And I'm ordering from Wal-Mart's drug store. They don't ask any question as long as it's not to help you find it on the shelves.

Holy fucking cow! My biggest was 100g (unmelted) and that was already a lot. I just can imagine the whole fucking city looking at the cloud...

I'll add more sugar in it to get more smoke with less nitrate. Probably a 60/40 mix as it burns smoothly. I'll spread it on a large surface, maybe making a drawing with it like Zorro would do (sorry for the shitty example...) then light the whole thing.

Yeah, what I mean was of course there are issues with containing and controlling it when it gets that big. At least if you thoroughly soak a small one it can probably be extinguished, but no such luck I imagine with a massive one. (I'm not sure about this, do check with someone else)

And as Moko said, too large and it becomes inefficient...or rather, more efficient, but we are aiming for inefficiency to produce smoke. So..yea.

Would be cool if you arranged a whole bunch in a pattern at the base of your hill and then lit them simultaneously. Then you could film from your high spot and, if wind was minimal, it'd look pretty cool.

I tought about doing a 10lb. one. I think you can buy 4lb. bags of sugar. Never got to it though. Wear I live it wouldnt attract much attention, if any.

I would make a bunch of small ones and get a team to set them off around town at the same time.
