Ethanol is the alcohol we drink and in moderately low doses can cause delusions of adequacy. Methanol, on the other hand is a poison which can cause permanent nerve and brain damage at fairly low doses. Methylated spirit is Ethanol with 10% methanol, violet dye and pyridine, which makes it taste horrible.
However, the most dangerous part of ethanol is that is very flammable and burns with an invisible flame and an ethanol mist would be an explosive mixture.
I like the idea of cold air - but I wonder what volume of air it needs to get enough temperature drop through adiabatic expansion to be effective.
