on the first day of school, a science teacher in my school took a mixture of chemicals or something and diped stuff into it (like a dollar bill n stuff) and she lit it on fire, but it didn't burn. anybody know the mixture?

a 50 -50 solution of alcohol and water with work. I use ethanol in class but isopropyl should work too.

water and alcohol
When the bill is soaked an alcohol-water solution, the alcohol has a high vapor pressure and is mainly on the outside of the material (a bill is more like fabric than paper, which is nice, if you've ever accidentally washed one). When the bill is lit, the alcohol is what actually burns. The temperature at which the alcohol burns is not high enough to evaporate the water, which has a high specific heat, so the bill remains wet and isn't able to catch fire on its own.
After the alcohol has burned, the flame goes out, leaving a slightly damp dollar bill.

my brothers showed me this once. its alchohal. if you put some on you hand you can stick your hand in the fire without getting burned.
DO NOT TRY THIS AT HOME!!!!!!!!
THEY ARE SCIENCE TEACHERS SO IT WAS SAFE.
I REPEAT DO NOT TRY THIS AT HOME!!!!!!!!
