The change in pressure that occurs when air enters the wider part of the bottle and comes out through the bottleneck cools the air. It seems uncanny, but the principle is simple. Blow on your hand with your mouth wide open. The air feels hot, doesn’t it? Now, blow on your hand with your lips pursed. It feels like a cool breeze.

And if you had the bottles installed the other way around, with the small opening on the outside and the large opening through a large hole, would it do the opposite and work as a heater of some sort?
