There is one tool that is sure to give you guidance if you get lost, a compass. But what could you do if you forgot to pack this useful tool in your survival kit? Easy! Float a needle on top of a standing pool of water. Well, there's a bit more to creating a compass out of a needle and some water, but you can do it right at home with just a few tools.
- Sewing needle
- Magnet (make sure it has a "north"/"south" distinction")
- Wax paper
- Red Sharpie marker
- Have you ever magnetized a needle? No? Well, there's a first time for everything. To magnetize your sewing needle, rub one end of the needle with the "north" pole of your magnet 50 times. Using a red Sharpie, color this end of the needle.
- Repeat this step, rubbing the "south" pole of your magnet against the non-magnetized end of the sewing needle.
- Using a pair of scissors, cut a circle about 1" (2.5 cm) in diameter out of the wax paper.
- Carefully thread the needle through the wax paper circle, as you would a needle into cloth. Don't run the needle all the way through, but leave the needle half-way through the wax paper with the needle lying flat on the surface of the wax paper. (See photo.)
- Float the wax paper on the surface of the water. The ends of the needle should be facing up with the middle of needle, on the underside of the wax paper, facing the water.
- While the needle and paper float on the surface of the water, watch what happens. The needle will rotate on the surface of the water! The red end of the needle, the end you magnetized with the "north" pole of the magnet, will point north.
