Easiest thing to do is put ice water in a pie tin in front of a fan on high. The air will cool as it flows over it.

You can make your own evaporative cooling using a fan and a wet towel. Hang a wet towel in front of the fan and leave the bottom sitting in a bucket of water. The fan will blow air through the towel and the air will cool down as it dries the towel. The towel will stay wet (mostly) with capillary action of the water up the towel. Make sure you do not do this around small kids and be careful.
