lol

I checked around to ge the materials to make one... very hard to get here in Canada. Down in the states, it would just be an affair of 15 min. Not worth the time AND MONEY for the result it gives. Plus the risk of it taking fire...

Honestly just stick with the ones from Kaboom or the distress ones. I know there are some people out there who think they are basement alchemists but not worth the risk.

Not to mention, as I've said in numerous other threads, making your own fireworks is illegal.

Yep, but it took me a decade of blood, sweat, and tears to get it! Honestly though if you've found your professional passion there's nothing better. It's like they say, "Find a job doing what you love and you'll never work again."

Don't think my job is all peaches and cream BTW. Hours, even days of setup fusing shells, schlepping heavy steel mortar racks strapped with high density polyethylene guns (and trust me, the 'high density' title is well earned), plugging electric matches, for ten to twenty minutes of fun. And then you get to clean up!

A couple years ago I phoned some garden shop here in Calgary and asked the guy if he had any potassium nitrate, he told me he did. I went down to get some of it, told the guy it was for a science project, and he gave me 5 pounds of it for FREE. I still have lot's of it left.

Also you don't need to cook the stuff, you can just make a 60/40 mix of KNO3 and sugar respectively, stick a fuse-or some other way of lighting it-into the mix, and light it up.

You can also make fuses by taking some of your 60/40 mix, throw in some water until you have a nice kinda pasty crap, and then soak some wool in it. Let it dry over night, and you'll have a nice cheap fuse.

I've made my own, and the first time i coulda gotten pretty hurt, and the 2nd time (a couple days ago) i put it into a pvc tube, and it went alot further than i thought it was. The way to make it so it doesnt burn as hot/slower is you add baking soda. The baking soda releases carbon dioxide when it is burned, and reduces the amount of oxygen therefore "limiting a reactant". The kno3 works as a oxidizer. I haven't taken ap chem yet (within the next 2 years) but yes the sugar burns very hot.

going back to my first experiment, i was stupid enough to use a glass jar to hold the liquid, but i didn't how how easily lightable it was. It doesnt light from the heat, but anything close to a spark lights it.

the online formula is normally 60/40 pno3 to sugar (by volume). i've read that if you add sulfur it'll make more smoke or something, but i've tried both, and havent done enough of it to see the difference. the more sugar you put the more smoke, and more kno3 the faster reaction. I've tried doing the equation for it, and i found the weights for a complete reaction, but i forgot it. i think it was like 3/1 sugar to kno3. One of the products (from my equation) was KNO, which i'm pretty sure is poisonous in some way or another.

For colored smoke, you can add rit dye or powdered dye for dying t-shirts. I've only tried this once so far, but you need to add the dye after your done heating it or the dye will evaporate while your cooking it, and it wont color your smoke.

If your going to do this, it makes alot more smoke when you melt it together, because it probably makes the stuff more concentrated with less air pockets.

And don't use anything glass, or anything that will break under pressure. I chose pvc because it will melt instead of shatter, and imo its somewhat safer.

the smoke doesn't rise more than 50 ft visibly. My yard is surrounded by trees, and it doesn't really rise more than the trees.

Oh and if you are going to do this, Be Safe. Keep a couple containers of baking soda around, or a fire extinguisher. I chose baking soda, because it works pretty well, and you can get it cheap.
