Are to you tired of cooling the entire house when you're only using one room at a time? With 103 and 105 temps looming in the Mid-Columbia, maybe you'd like to drop the A/C bill down a bit and try this DIY personal air conditioner. The funny this is, I had a glass of Diet Dr. Pepper filled with ice the other day while I was in the garage. I also had personal fan running to circulate some air. When I set my icy cold glass of pop behind the fan, I could feel it blowing cooler. That's the whole idea here, but with a longer lasting effect and cooler air than my ice filled glass, for sure.
