I saw these clear tubes at Spencer gifts, you know the one that has the light and the plastic fishes floating inside. I was thinking if I could increase the airflow so that much more bubbles flow through it, wouldn't it make a pretty cool cooling tower for a water cooled computer?? I'd also try to make a lot of little bubbles for better surface area for the air that goes through. And it can be lit up (although dimly so that it doesn't heat up) and make a pretty nice piece of decoration or something.
