1 lb Potassium Chlorate
1 lb Zinc Dust
1 lb Sulphur Flour
And I mixed it up in my living room, on a big piece of brown roofing paper, with plastic gloves on. I used the 'just a pinch' measuring spoon to measure out
44 Potassium Chlorate
15 Sulphur Flour
40 Zinc Dust
and 2 crushed charcoal.
I mixed it in an empty butter container. I went out onto the street and placed a tractor disk on the street. I put a handful on the disk, and set the tupperware down on the ground. I lit it with a lighter.
It flared up a little, almost burning me - and then it ignited the butter container full of the extra, which REALLY flared up, and it definitely put off a really big cloud of smoke. Really fast. Whoops!
So basically, it works, albeit a little fast. So now I have to figure out how to slow it down. An inert substance such as playa dust might be a good mix-in, or perhaps I could pack it into a long narrow metal pipe that could only let it smoke out the end - it would get very hot, on the other hand, the lack of oxygen would keep it going for a very long time.
