I'm not sure if this is the right section... But Assume you have a medium sized box (about as big as a large desktop computer) inside a room. And inside the box there is a jar of water that is significantly colder than the outside temperature. How would you prevent water condensation from occurring inside the box? Rules (the ones I can think of so far..): - You cannot lower the rooms temperature to match the water. - The solution should be semi-reasonable. I have a few Ideas but I'll like to see if anybody else can come up with them first. Thanks.
