Wow, I might try this next time. It washes of in rain though, right? I've seen people tape thermal blankets (aluminum on plastic foil) to their Windows.

You can also use yoghurt - exactly the same principle, it's basically "casein paint". Hanging blankets on the outside of the window also cuts heat transfer through the window by ~90%.

When it's too humid for a fan to cool me off I have these small wearable ice packs that I strap inside of a collar around my neck, and wearing them in front of a fan gets me through the really hot days. Fan is still necessary since you'll sweat a ton when wearing one. The ice lasts about 30 minutes, so you'll need to constantly be swapping packs to recharge, but it's relatively cheap.

I'm going to experiment with this idea, basically swapping the water for saltwater makes the icepack freezing temp ~18C, it lasts longer, and since it re-freezes without needing a freezer you can do things like make large ice-blankets that actually work (and not those useless gel things that instantly warm up).
