Created flashpowder from 70% Potassium Perchlorate, and 30% 400-Mesh German Dark Alumium powder then subsequently blew shit (mostly earth) up. I also set a lot of stuff on fire. I created Molotov Cocktails out of gasoline and styrofoam and threw them at a block wall of a barn-ruin in the back yard. I also remember creating a Napthalene charge(think cardboard paper-towel roll stuffed with ground up mothballs sitting atop of some Black powder) that was suppose to create a big fireball and though I had no black powder prepared, I did have some excess flash powder I needed to get rid of so I used that. -For the briefest, loudest moment my buddies and I lit up the night sky.

--It was dangerous back then but it was before 9/11 and a visit from the feds was highly unlikely. Afterwards it became much harder to acquire German Dark 400 Mesh Aluminium Powder and today I would wholeheartedly expect a visit from an Alphabet agency. I did scald my face when nickel(bottle)-rocket fuel (made of carmelized sugar and potassium nitrate) ignited in my face as I was melting it together.
