Swamp coolers are not complicated pieces of machinery.
Homemade swamp cooler box fan.
A styrofoam cooler makes a great diy air conditioning box as the holes are easy to cut and the coolers are cheap to buy.
This video demonstrates how cool the air being circulated can be.
Turn on the fan and put your bottles in front of it.
Ok where i come from it gets hot.
So hot that beer evaporates while in the bottle also the fact that my room gets a lot of afternoon sun does not make for a cool night in summer being the person i am i hacked an old newly bought bucket to create.
The air will cool down as it passes around the bottles.
They are essentially fans that blow air through pads soaked with water.
A table fan or box fan will work best but you can use any fan you want.
