not homemade, only factory made haha. i'm a chemist , i got the arsonist merit badge to boot lol.
i make my grenades with a pound of pure potasium mixed with harmless vinager.....or maybe it was baking soda i was supposed to use? ....
oh well, same thing lol.
ya, pyro stuff is mighty dangerous. but if experienced it makes for fun stuff.
(obviously i'm no chemist. but my uncle kinda is, we once thought of painting a ducks bottom with potasium and watching it land in the lake hahaha. now that's funneh) kinda trolled.
