if i was to put the KNO3 and sugar mix into like a nail can and then seal it like a tennis ball bomb or something like that, but still have a fuse, will it explde or just burn through its container?

I don’t think the stuff burns fast enough to explode, per se. If you put it in a strong and sealed metal container it might rupture it, but my guess would be it would be a slow tear and not an explosion. You could try powdering it after you melt it, though, and find out if it explodes that way.

this reminds me, does it work if you take a tennis ball cut a small hole in it, stuff it full of strike anywhere matches (the heads) tpe it back up to where it is nice and tight. then throw it…will it explode? or just burn…

Well, that lame AC tennis ball thing does something along the lines of “100 match heads igniting at once” ever lit a match chaffin?

in the archives it says to use like a soup can with exhaust holes to contain the smoke bomb, it seems that the smoke bomb stuff would burn strait through the can, will it? also will this stuff light with an igniter that is used for lighting rocket engives? i m trying to set up a remote device.

I used to put the charge into a soup can, then put a large coffee can upside down over the top and punch holes around the edge with a juice can opener.  For a smoke composition, you want more sugar than normal to give you an oxygen imbalance… only partial combustion.  Particulate carbon will be liberated, and if you use the above-described setup, the second can allows the carbon to cool enough before hitting air so that it doesn’t catch fire.  You get *much* more smoke in this manner, and less chance of catching surrounding objects afire.

more sugar? like 6kno3 5sugar or 6sugar 5kno3?

Anything producing enough gas in a contained area will explode or rupture the container. I would just adjust the ratio of chemicals to find the best mixture. Or you could just do a little formula to find it out. For that you would need to understand moles. oh well
