vanillity Posted April 25, 2006 Share Posted April 25, 2006 what would be a way to make some small firework sized explosives (legal where I'm from) using simple methods and chemicals? probably even just some chemicals that make cool effects when mixed? (gas, colors etc.) if any of this is illegal to answer/post please delete and sorry for the problem. -EDIT- please move to applied chemistry, sorry for the mistake.

vanillity Posted April 25, 2006 Author Share Posted April 25, 2006 I just heard something about salt-peter, sulfur, and powder sugar. Link to comment Share on other sites More sharing options...

akcapr Posted April 25, 2006 Share Posted April 25, 2006 does anyone remember/know the right proportions by weight for a sugar-kno3 propellant mixture? or perhaps a reaction equation? Link to comment Share on other sites More sharing options...
encipher Posted April 25, 2006 Share Posted April 25, 2006 The mix is 60% KNO3 and 40% Sugar. However it can vary depending on what you want it to be like. Please do not attempt to make this if you don't know what you are doing or you aren't too good at following safety guidlines. If heated too much the mixture can ignite and cause a big mess.

[w00t] Posted April 25, 2006 Share Posted April 25, 2006 The mix is 60% KNO3[/size'] and 40% Sugar. However it can vary depending on what you want it to be like. Please do not attempt to make this if you don't know what you are doing or you aren't too good at following safety guidlines. If heated too much the mixture can ignite and cause a big mess. 60/40 is a smoke mixture 65/35 and 75/25 is the rocket mixture i personally use 65/35 + 0.5% iron oxide The the combustion would consists of Co2+ h2o + k2co3, all which arn't harmful (doesnt mean its good for you). the correct reaction equation was posted on another thread here, dont remeber which If you want cool effects use charcoal instead of sugar because you cant see effects when your using sugar (atleast for me) and a cool effect would be a modified blackpowder that burns slower with added aluminium powder. heres a video of mine: http://www.youtube.com/watch?v=5K5GzHJusU4 Link to comment Share on other sites More sharing options...
encipher Posted April 25, 2006 Share Posted April 25, 2006 My bad, didn't read the question carefully =\ Link to comment Share on other sites More sharing options...
