With summer coming on, my wife asked me to come up with some way to keep cool during hot summer nights. This is what I came up with. I am sorry there are not enough pictures to go with this instructable, but my son killed my digital camera(he wanted to see if it would float in the sink...sigh)this was built before I got my new digital camera. I do think that this is straight forward enough that you get the idea.

Get a cheap cooler from a thrift store or second hand shop. Find a conduit like a dryer vent hose and hold it against the cooler about an inch or two up from the bottom. Next mark around it with a sharpie,drill a hole and cut out the circle with a jig saw.
