    Hello,

    I want to make a smoke bomb, but i do not have any KNO3, so I want to know if I, in some way, can use HNO3(aq) instead?
    I think it is only the nitrate mixed with sugar that causes the smoke.

    to make the smoke bomb you need solid KNO3 (can easily be bough from a hardware store as fertilizer) or off youtube for a purer mix.

    You'll need to melt it with sugar in a pan. (do it outside)
    Then put it into a can, blobs, whatever, insert fuse, and let cool.

    When it's cool, just light the fuse and it should give off a huge cloud of smoke.

    This sounds dangerous. Heating potassium nitrate with a reducing agent like sugar could cause sudden violent ignition. Very risky!

    Certainly more dangerous than making a baking-soda and vinegar volcano, but I doubt it’s much more dangerous than grilling some burgers with a charcoal grill and lighter fluid. The mixture will certainly burn very quickly, but I don't think it could detonate. As long as the mixture isn't placed in a closed container, it's outside, there isn't anything flammable around to catch fire, and you're careful to not burn yourself I'm not really sure what could go wrong.

    I'm sure you could accidentally light yourself on fire or burn your house down if you aren't careful. But again, that's also true of grilling with charcoal and lighter fluid, which most people don't consider particularly dangerous. If lighting a fire outdoors and containing it in a metal container is the riskiest thing you ever do, you’re probably leading a pretty safe life.

    Nitroglycerin... flash powder... and light light light light light light tissue paper. Soak the tissue paper in the nitroglycerin, than wrap the flash powder with the tissue paper.

    No it won't detonate, but a sudden violent ignition, by which I mean a flare up, is very possible. Could be dangerous if quantities are large enough, or if one is bending over it to get a look when it goes off. Burns and blinding are a real risk. It's the sort of thing I might have done in my pyromaniacal teens, when I was putting home-made gunpowder in pipes, pouring yellow phosphorus dissolved in carbon disulphide onto sodium chlorate, chucking inch cubes of sodium into water (was tempted to try a whole stick, just as well I didn't), or making thermite by the kilo - with MnO2. I do NOT recommend these activities to anyone who wants to stay alive, or at least free from third degree burns!

    pyromaniacal teens hell yea, I almost burned a whole field down... with friends and gasoline.

    Instead of using Nitro-tissue lighter, that will definetly blow in you hand (while lighting) why not use a firecraker fuze, not that expensive, and not as dangerous.
    I haven't come to fight my word, but to find the truth.

    You can do virtually anything safely if you're careful and take appropriate precautions, and virtually anything can be dangerous if you do it carelessly. Many people work with explosives or deadly poisons in their jobs every day without accidents, and many people kill themselves trying to get their stuck piece of toast out of the toaster with a fork. It's simply a matter of determining what precautions are necessary.

    Yeah, heating a mixture of sugar and a KNO3 by yourself over an open flame in your basement next to a pile of old newspapers with your face three inches away is probably not safe. Heating it outside and away from anything flammable with an electric hotplate and a double-boiler, safety goggles, a fire extinguisher, a fire-resistant glove that goes up to your elbow, and a friend to observe/help if anything goes wrong is probably safe.
