Cheap DIY Air Conditioner

I built this completely with materials found around my house.
This is NOT meant to cool down a whole room, it just creates a nice cool breeze. 

Materials Needed:
Coleman Personal8 Cooler (or similar)
Small, cheap styrofoam cooler (usually under $10) will also work. 

3 PVC elbow joints, about 1/2 in. ID (around $1 each at hardware store)

Drill with bit same size as OD of PVC elbows

Computer fan (about $5 from radioshack)

12v transformer* (not sure where to buy these...)

6 empty gatorade bottles

Duct tape (about $10 from radioshack)

Extension cord w/ switch (not totally necessary, but nice to have)

Xacto knife

*transformer only necessary for a 12v fan, you can get a different one for different voltage fans of just install a plug if you have a 120v fan.

Put the fan up against the back of the cooler, mark with pencil around the outside of it, and cut out a square hole for the fan. Push the fan into the hole. A tight fit is good; it lets less air escape. 

With your drill, drill 3 holes in the lid for the pvc elbows. Insert the elbows in and secure then with duct tape. 

Fill empty gatorade bottles with water, and then freeze them. Once the water is frozen, remove them from the freezer and tape them together like a six-pack. You can modify this to compensate for different cooler sizes, my cooler just happened to fit them perfectly. 

Pretty self-explanatory... you can just twist the wires together or solder them if you are really committed. 

Put the frozen bottles into the cooler.

Turn on the fan and feel the cool breeze across your face...
