I got this little swamp cooler to cool my 9 by 10 room from 75 degrees to 65ish degrees in about 1 hours with the doors shut and the windows shut and blinds shut.
What I have found that works just as good is just take a spray bottle and spray the pads manually. Also the colder the water the colder the air!
Step 1: Parts
1. Approx. 28X32 sheet of Coroplast (Plastic Cardboard)

5. Lots of duct tape
6. A Y split off for the tubing
7. Synthetic evaprotive cooler pad I recommend the DIAL 28 in. x 34 in. DuraCool Pad for Evaporative Coolers from Home Depot DO NOT USE ASPEN FIBER COOLER PADS TOO THICK AND SMELL FUNNY
8. A transformer that will run the fan Depending on the voltage the fan can handle
9. Hot glue sticks
10. Electrical Tape

Step 3: Take the squares
Step 4: Put the squares together
Step 5: The bottom
Step 6: The top
Take the top and cut the hole for your fan. Once hole is cut make a air tight seal with duct tape or hot glue. DO NOT ATTACH THE TOP TO THE REST OF THE CUBE.
