Good Work! 9/10

alwinovich: no i wasnt injured except for a few little burn marks where hot pieces hit my skin. i was mixing iron oxide and aluminum oxide(thermite) and luckily it was just a little dose when it accidentally pre-ignited. what were you using?

10 freakin grams of Armstrong's mixture? Do you realize that this composition is far more sensitive to friction and impact than organic peroxides, and has a good record of igniting spontaneously due to the reaction between KClO3 and sulfur? It could have easily ignited while you were mixing it, taking off your fingers and severely damaging your hearing. Playing with Armstrong's mixture in the first place is incredibly stupid, but you win the dumbass award for mixing up enough to take your hands off at the wrists.

If you want to mess with flash powder, at least use a stable composition such as standard 70/30...

We'll get back on topic, I was just trying to save the ignorant kid his hands, and the pyrotechnics world some slack. When dumb people blow off their extremities, it just makes it harder for the real amateur chemists to pursue their hobby without restrictions.
