what makes the best flash powder?potassium permanganate or nitrate?
currently performing operation "shoe candle" , for yowee.
this operation is basically videoing the destruction of various fruit using flash powder or hmtd in a small 1-2ml glass vial.
now, i have chosen my prefered explosive to be flash powder because after seeing the damage hmtd does when detonated in this way, i became frightful for my own safety, considering it lifted 1kg of dirt 30cm into the air and destabilizing it and making it fell as if it were dug up and loosly fille din again.
i have come across a slight problem
because i cant readily make aluminim powder enough to experiment with flash powder concuctions, and also i have about 4kg of finely powderd potassium nitrate lying around, wheras permanganate costs $10 for 25g at the pharmacy
i would like to ask you instructables members,
would flash powder made with potassium nitrate combust better than flash powder made with potassium permanganate
the current mix i am using is 3 parts permanganate / 2 parts aluminium powder/ 1 part sulfur
apparently this is the recipe for the old M-80's firecrackers
i want to know if a equal or more powerful mix can be used by using potassium nitrate
whoever answers will receive a best answer from me
