Energetic smoke comp.

I just finished testing my new smoke composition. and MAN is it energetic! I stuck a piece of visco fuse into a baseball-sized lump and it burned for about 1 second with a bright read flame. A large mushroom cloud of smoke (about 10 feet across) rose about 40 feet into the air until dissipating... :D
Anyway, heres the "recipe" (for lack of a better word):

1/3 cup of KNO3

1/4 cup plain white sugar

1/2 cup of water


Extra materials:

Small pot

Spoon

Cookie sheet*

Non-stick cooking spray*

Rubber gloves*

Visco safety fuse*

*optional, but makes the job easier... :D

Synthesis:

1. Bring water to boil in the pot
2. Add your KNO3 and stir until completely dissolved
3. When the solution comes to a boil again, add sugar and stir until completely dissolved
4. Boil down until it becomes a white, pasty substance
5. Stir until it becomes a light peanut buttery color
6. Put onto greased cookie sheet and knead and shape with greased rubber gloves.
7. (Optional) Insert a piece of Visco fuse into the composition before it hardens.


The end result is well worth the time! (~10 mins)

Can't you mix the two powders for a less powerful smoke bomb without the risk of blowing up your kitchen?

A-98, I don't know about underwater, but KNO3 is definately an oxidiser.

F_S, the odds of accidental ignition are minimal, the only way for this stuff to accidently ignite is if it bubbles over, and you can prevent that with a bigger pot. I alway use a small pot but I have a very strong fan built into my stovetop that sucks away any bubble over ignition...

Energetic? This is a pretty tame smoke mix.
I wouldnt call anything that puts out less some than hexa/zinc comps energetic in the slightest :(

A tip though, black powder, 5-25% to taste, will increase burn speed, and make a much denser cloud of smoke.

I prolly should've metioned this before, but I meant it burns SUPER fast for a KNO3/sugar mix. When I use less KNO3, the mix burns slower and produces ridiculous amounts of smoke, even in small quantities.

I wish I had a ball mill... I have the chemicals to make 10-15 pounds of black powder, but I just dont have a mill... :cry: What I really want are just some good oxidizers, such as perchlorate, so I can make some flash powder.

Are you really in to pyrotechics BC?[/i]

Yes, and I can say that you certainly don't strike me as someone who should be making or using flash powder. 2km/s is pretty deadly.

Oh, believe me, I won't actually make the stuff, but I wish I could. The only real pyrotechnic device I have made is a simple blackpowder salute rocket. When I get older, I want to be a pyrotechnition and maybe even become a member of PGI. *sigh* Dreams, dreams...

K. Sorry to jump on you, but ya never can be too cautious.
I am more into the chemical synthesis side of things, MEKP, PETN, etc.

KK. I would definately chat, But i'm not allowed to download either chat service. My dad is way too lazy to get the backup discs for our new computer, and he won't let me download them until he gets 'em... :evil: By the way, I know what PETN is, but what is MEKP? I know MEK is methyl ethyl ketone, but is the P for peroxide, like AP?

hmm...yes, that is a problem.


couls you coat it in wax? or would that just melt and then expose the "bomb".

i dont know why im asking, but it would be pretty cool to burn one underwater.
