Bored.

I was bored and really hot at the house, so I made homemade airconditioning. It's my existing fan with some copper tubing ziptied on the back, with an aqarium pump submerged in a cooler of ice and water. The water is pumped through the copper tubing on the fan and the fan blows cool air. It's actually a 2 stage system, but I'll spare you the details.

Here you go. No big deal:
