When we were kids, we were surprise to see that a lemon can light up a bulk, from which we learnt that mixed liquid is able to produce electricity with metals. By this theory, I design this water flashlight which using liquid as power supply. It will be convenient for travelers and explorers, because it could be easily recharge by water or any other liquid. And it is also environmental-friendly.
