2010-05-13· Out of an abundance of caution, I decided to mix the chemicals inside each M-80 on a binary basis. I weighed out 3.5 grams of potassium perchlorate, poured it into the M-80 with a small funnel followed by 1.5 grams of dark aluminum powder. After gluing on the other end cap, I gently shook the device several times, turning it end for end to mix the chemicals.
