that thing is crazy cool lol. i wonder how it works...
1. Hold your hand in front of your face, with palm facing you.
2.
Use other hand to propel the hand in front of your face toward face Blow cold air emitted from your mouth onto said hand.
3. .....?
4. You now know how the fan works. Or buy one of those battery-operated handheld fans.
And no, that's way too much for something that blows air. Speaking of overpriced machines that blow air, I was at a mall and I saw this phone booth-sized machine that's supposed to "simulate hurricane force winds". Well, I was stupid to waste $2 on having a bit of air blown in my face and clothes. If I wanted to experience hurricane force winds, all I have to do is wait a couple of months and something is bound to come this way.
