A few days ago i read online that you can make a compass with a needle. So I decided to try it this morning. The instructions said to get a small needle and rub it one direction with a silk fabric to magnetize the needle, then take oil from your body (like where you nose meets your face) and rub on the needle this helps it float on water as the sharp end of the needle adjusts it self to point North. It took a few trys but it works, I substituted a little butter to make the needle float. After following the instructions i gently set the needle on the water with the sharp end pointing east to make sure it would direct it self and it did! I felt like a Myth Buster!
