Introduction: 15 Min. Tower A/C
In this instructable (my first) I will show you how to make a simple desktop cooler capible of putting out air up to 30 degrees cooler than ambiant temperature. I will go over a list of the materials, how to assemble it and how to operate it. Not the prettiest thing but when its 90 degrees inside at night, who cares! Also do note that although there may be slightly similar ideas and designs this is my own original idea.
Duct Tape Screwdriver
9v Battery Hacksaw
120mm PC Fan Cutting tool
Sharpie (for marking) 2in. Holesaw
Window Screen (or equivalent) Razor saw (or something else sharp)
4" pipe, 10 inches long
Pet Water Dish (4 in. is great)

Step 2: Cut Up the Pipe!
First cut the pipe in two pieces one 4 in. and the other 6in. Then you will want to drill a 2 in. hole in the middle of the 6 in. piece (the longer one) of pipe. this is to let the cool air out.
Step 3: Chop Up the Fan!
Next you will want to cut and file off the corners of one side of the the 120mm fan so it will fit easily in the top in the smaller piece of pipe. Note, don't cut off both sides or it will fall in to your AC. Dont make the fit to tight eather or you can't put ice in the unit.
Step 4: Add the Screen!
Now cut a piece of the screen to fit on the big piece of pipe.Tape it on securely. Then tape the two units together with the screen part between them (The top and bottom pieces of pipe).
Step 5: Make the Drip Tray!
Now use the same process described in the previous step to put the screen on the top of the pet bowl. Then tape it to the bottom of the main unit.
Step 6: Finishing Up!
By now your unit should look something like this. All you have to do now is tape on the 9v battery,fill the top container with ice (leave a half inch for the fan), place the fan in, plug it in and finally cool down!!!
We have a be nice policy.
