We are just getting started into the summer heat. If you don't have an air conditioner, this is an inexpensive way to create your own. Take an old plastic or styrofoam cooler. cut 2 holes in it and place a fan in one hole and a PVC plastic elbow in the other. Place some ice blocks in the cooler, turn on the fan and sleep more comfortable at night. Watch this video. It will walk you through everything. I prefer styrofoam because you can cut your holes with a steak knife. easy. Good luck.
