 I want to show you one more time what I did, and let's see if we can figure out what's happening chemically. You have the flame, and then after the flame, see that steam coming off? Our mixture here that we're calling our fuel is actually 50% ethanol and 50% water. So when we dip the $10 bill in this mixture, the water is absorbed by the paper that the $10 bill is made of, and then when we burn the alcohol, the alcohol flames and produces a heat, but there's not enough energy to evaporate all of the water, and therefore the water is actually protecting the $10 bill.
