An interesting phenomenon applicable to mining and demolition. Non ideal binary explosives can see a net increase in VOD 40-100% when confined instead of being open air. Compare that to 1-5% increase for ideal legacy explosives rdx, petn, tnt.

Logic being a faster reaction zone due to an ideal explosives having close chemical contact from the get go. Where confinement for non ideal explosves allows to speed up the reaction and reduce critical diameter.

Im taking a piss in the title but apparently Ukrianians devised the same thermobaric tech like the kid who was posting on here trying "thermobaric mixes" to break in or break out of some wall. Lol

Discuss pro and cons

I wanted to perfect emergency/survival kits for making pull fuse igniters for emergency starter kits or road flares/emergwncy signals. The match striker set up is pure amateur hour and not worthy of a reliable device. Inv Incarnate's choice and kits that he sold seems to go off a little too hot for my liking. I just want a hot pyrogen action not a gun primer. He uses kclo3/ant trisulfide, sulfur, glass for main composition. Friction wire comp isnt as crucial it has red P, s, glass. In trying to slow it down im thinking of going with kclo3 and just antimony, and for striker try red P with Manganese dioxide(www2 era friction ignition formula). If anyone played and perfected friction ignition set ups id like to hear your 2 cents.
