Smoke Bomb

I figured I'd make a tutorial on how to make a proper smoke bomb:

Thing you'll need:
-Potassium Nitrate (powder)
-Granulated Sugar (the regular kind)
-A Stove
-A Disposable Stirring Device (cardboard piece, wood stick, etc.)
-A Toilet Paper Roll (or soda can, cup, etc.)
-A Pot (no not a toilet)
-A fuse (optional)

How To:

First of, if any of you are wondering, Potassium Nitrate is easily available on http://www.ebay.com/ for a reasonable price. Once you have the Potassium Nitrate, you need to get all your materials gathered at the stove. It doesn't matter how much you make, only that the ratio is correct. You need 3 parts Potassium Nitrate and 2 parts Sugar. So if you put 3 tsp of Potassium Nitrate you would put 2 tsp of Sugar (or any measurement).

Once you have the proper amount measured out, then put both powders into the pot. Turn the stove on medium and stir it constantly. IF YOU DO NOT STIR CONSTANTLY IT WILL EXPLODE!!! Please stir guys, I don't want to be responsible for any burned down houses. So as you stir it, it will eventually (be patient it may be a few minutes) start to clump up. Keep stirring and it will quickly become a thick sticky orange-brown mixture. Keep stirring until it looks like peanut butter. Then use your disposable stirring device to pour it into the container. Once you're done with the stirring device, set it outside or on some paper you wont need so it doesn't make a mess. Also, make sure you're not going to need the container again, as it will most likely burn or melt. The mixture is very hot at this point, and you will have to be careful not to burn yourself. This is not my picture and is temporary until I get a camera, but that is what the finished product should look like.

Place the fuse in the middle right after the mixture is completely poured in. You need to put in the fuse before the mixture hardens (which it does very quickly). If you do not have a fuse, be sure that your match/lighter can easily reach the mixture. Also, fuses can be purchased at the following address: http://www.cannonfuse.com/ By the way, fuses are not considered fireworks by law and are 100% legal in all 50 states. For more info see my post on fuses.
Once the mixture has hardened go ahead and take it into an open area where there are no people around (not that I do that anyways). Set it down on the ground and light the fuse or mixture. It should burn quickly and very well. If you have any issues then send me an e-mail.

Afterwards, you may notice that your pot has clumps of the mixture still in it. No need to worry this is completely normal. What you need to do is take the pot outside and light the clumps on fire till the pot is completely free of the mixture. Do not worry about damaging the pot, if it is metal then it should do fine. Afterwards you should be left with some black ashes in the pot. This should wash out easily. As for the disposable stirring device, just light that too, then throw it away.

Thanks for reading! When I get a video camera and/or digital camera I'll put better tutorials on.
