How to make a Potassium Nitrate (KNO3) Smoke Bomb without melting it

on 4/7/2009 Of course, my son thought this was the coolest thing ever. I had to tell him that you were pretty cool, too.

on 1/15/2009 holy smokes this is crazy cool..

on 11/28/2008 highqualitychems.com has some good pyro grade stuff otherwise I get it all on ebay cuz it's really cheap there and also pyro grade. Btw it only covered about 500 feet wide behind the trees in that vid. Too bad I didn't really catch that part on camera. Btw the heat was so hot it burnt my face slightly as I filmed it from about 15-20 feet away.

on 7/7/2008 BTW, to all the reader out there - Toilet paper rolls work best - unless you're gonna pull off a massive one like the 17-pounder in this guys video lol. Never know when you're gonna need a smoke screen in a wide open 100 acre plain. lol - btw - can you tell some sites where I can get KNO3?

on 7/7/2008 Why someone might need/want to know this? Because it's a fun and convenient way to create a large quantity of smoke, for use either as a signal, in emergency situations, or as cover for an airsoft or paintball war. Or maybe if you just wanna make smoke for the heck of it. Or if your a do-it-yourself kinda person who likes to do things hands-on, or just want something to say "Hey, I made this!" How he knows this? Well, theres lots of other how-to guides of how to make a smoke bomb, (This being the most helpful and informative - Thumbs up!) or maybe he just payed attention in chemistry class, and had a few goes at it until he got it right!
