If I fill a steel thermos with water and put it in the fridge, the water still doesn't dry out even after months. I don't know what that proves but I bet scientists will figure it out. I'll be awaiting my Nobel Prize.
If done in a controlled environment, it's apparently very tasty! I recently stumbled upon a tutorial somebody made recently about how to make watermelon jerky with a dehydrator. Apparently the flavor gets significantly sweeter. He was making it for hiking/survival purposes, so removing all the water weight lets you pack a lot of lightweight nutrients, too.
