Long story short though it was so long ago I can close my eyes and still see one part of the show. The person took a small petri dish and filled it half full of ethanol. Just plain old grain alcohol. He got two of our students to come up on stage and light the alcohol with a lighter and tell us about the very light blue flame assuring us that it was burning although we could not really see it from the audience. Then he climbed a 20 foot step ladder and stood on the second to the top step and poured a one quart thermos bottle of liquid oxygen down onto that small dish of burning alcohol. Without being there you can not imagine the resultant fire that shot strait up out of the dish like the exhaust of a rocket....... it set the ends of his tennis shoes on fire for a second or two. I wouldn't wish you to be old as me, but really you shoulda' been there. Link to comment Share on other sites More sharing options...

Charcoal, coal. I used to have a hand warmer that used some form of kerosene that retarded the oxygen available and it gave off heat with no flame. Rusting of iron is technically very slow burning.
