Repost but relevant
A few years back a fellow b3tan and I decided to knock together a few smoke bombs. I ordered some potassium nitrate and fuse wire from eBay and mixed it at a 3:2 ratio with some sugar. We put it in a pan at a very low heat and stirred continuously until it was the colour and consistency of peanut butter. We then spooned it into bits of toilet roll tubes cut into three with foil wrapped around the bottoms. We poked a hole in the still malleable paste with a pencil. When they were solid (which doesn't take long) we put a piece of safety fuse in each held in place with a bit of cotton wool. We set one off in the garden and they worked very well. Loads of thick white smoke and the reaction was volatile enough to burn the foil. Once we had used them all up we decided to make some more. Same recipe except this time I cranked up the heat to speed it up. I remember stirring and suddenly feeling a tiny sticking sensation like striking a match and then the contents of the pan exploded in my face spraying molten sugar and thick white smoke everywhere. Somehow I was unharmed and thanks to the stone flooring in the kitchen the floor was ok where I had dropped the pan. The kitchen sides had a few speckles where the molten sugar had melted them but it was pretty much ok. We opened the back door and waited outside for the smoke to clear, except it didn't. I went back inside and opened every window and door and stood out the front to convince the neighbours the house wasn't on fire. After about half an hour the smoke had almost cleared and I had managed to clear all the mess off of the kitchen floor. All seemed well then the wife arrived home. "Why are all the windows open she asked" We told her we were just airing the house out she eyed us suspiciously and said she was going to make a cup of tea. We had gotten away with setting fire to her kitchen! She went to the kitchen and opened a cupboard to get the tea bags.

It was full of thick white smoke.
