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.

Signing UpStep 1Cut Hole For 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.

a good improvment could be to add salt to the water bottles so after they've been froven they'll take alot longer to defrost

For a Fan you can use a computer case fan alonge with a power supply from a computer also. So next time you are scrapping out your old computer save the case fan and switching power supply. That way you are only buying the pipe & duct tape for your air conditioner making it a cheep build. Regards, PG
