I recall seeing a presentation, as a child, at the Franklin Institute in Philadelphia. Some of the entertainment consisted of:
A $100 bill was set on fire yet not consumed...a balloon filled with Hydrogen was rigged up to explode...and then the fellow putting on the show held a handful of corn starch, put a match to it, and tossed it in the air. That's when I learned that corn starch is quite flammable.
