The above video amuses me: They state do not try this at home, but they apparently did. They obviously didn't know what they were doing, because if they had, they wouldn't have risked their friend (or at least severely burning him).
Does anyone know the percentage chance that this will happen if, say, I took a cup of flour and use a shaker (or just a shaking motion) to spread it out into the air? If I wanted some flour to combust, would I be better off (not in health, in entertainment) to just use a match?
Oh, and yeah, I am 13, but I am a bit more mature than other people I know that are my age. I'm glad they don't know about this site, because if they did, they would already be . (Seriously.)
Thanks in advance!
