How do I keep my apartment cool WITHOUT air conditioning?

I live in a two-room efficiency (so classified because of the lack of a separate living and bedroom). The bedroom has an air conditioner, which has been on most of the day, brining the previous 95 degree room down to a more manageable 80 degrees. The kitchen isn't so lucky. No AC in there. I've been living off of graham crackers and watermelon all day because they're the only two things I have in the house that don't require cooking. The kitchen windows are all open and I have a big box fan creating a cross-breeze, but it's still about 90 in there and humid. Way too hot to cook. Now I'm starting to feel sick because of all the carbs I've eaten without any protein. Please tell me: how do I cool the kitchen down without any AC???
