Finding water using a clear plastic sheet:
Dig a hole in a location that receives heavy sunlight. Dig it large enough to that the entire plastic sheet will cover the top of the hole. As the sun traverses the sky during the day water will condense out of the ground and stick to the underside of the plastic sheet. Place a rock in the middle of this sheet so that all the water collects where the rock is, and it will drip down into a cup that you place in the hole.
I'm just throwin something new out there instead of putting down my specific skills.
