Homemade Evaporative Cooler (Swamp Cooler)
What I want is some cool air! This guy put together an interesting contraption that makes cool air.
This is very good. I would use freezer gel packs. These would hold the cold a lot longer. I would have three sets of packs and rotate them about every eight hours. Also bottles of anti-freeze would be good. Using raw ice is not practical. There would be the need for water drainage, and possible bacteria accumulation with the water and air.
