Procedure:

1. Mix sugar and potassium nitrate together into any ratio that you want.

2. Put a fire to the mixture and watch it ignite in smoke.
<p>Hey mate,</p><p>Appreciate you maybe trying to help, but this is highly irresponsible.<br>&quot;Any ratio you want&quot; - This is HORRIBLE advice.<br>Anyone, with little experience &amp; even plain high school education should be able to clearly say that this is incorrect. <br>In a wrong ratio, stated in another comment it can be somewhat rocket fuel.<br>Potassium Nitrate &amp; Sugar can also be in a ratio for some explosives too!<br>Also, this is for anyone wanting to make one of these.<br>Use a 50% Potassium Nitrate, 40% Sugar and also 10% Baking Soda ratio.<br>This will achieve a nice thick smoke out of the bomb, baking soda slows down the burn so you'll get a longer lasting smoke bomb.<br>For the colors, you can use colored oil crayons.<br>By the way you should measure in weight &amp; not volume. (Grams, not cups.)<br>Bonus tip: Use a portable outdoor burner on low, as if the mixture catches fire it will have a lot of smoke and you don't want that in your home!!<br><br>~ Nelson, a new player to the game haha.<br></p>
<p>As nkz75 said, your instructions are so vague as to be dangerous. Did you know that potassium nitrate and sugar, when mixed in a certain proportion and contained, are also used as rocket fuel? </p><p>You don't warn people about the kind of container that SHOULD be used, you don't warn what temperatures to keep it under when mixing it, and though I can't be sure, it looks like you ignited it only a few steps away from your house.</p><p>You should take this down until you can refine it into something safer for other people to follow.</p>
<p>You sound like a moderator. If you are an expert in this type of stuff then inform the viewers in this comment here.</p>
<p>Hello.</p><p>I know we should be nice at our comments. But I must leave a warning...</p><p>Mixing sugar and potassium nitrate on the fire is dangerous, and unless you know what you are doing, you are endangering yourself and others.</p><p>Maybe you should stop copying things from other sites because that can lead others to dangerous situations. Or at least inform yourself better first!</p><p>I will try to make an instructable the next time I do smoke bombs, I hope it can help you to get some more info on that.</p><p>Best regards!</p>
lol
Potassium nitrate and sugar do not produce yellow smoke. You have copied the images from here :http://www.skylighter.com/colored-smoke-bomb-kit-yellow.html <br>This is a commercial site which sells smoke bomb kits. Your &quot;recipe&quot; will only produce white smoke.
