Here's a potentially useful tip that I just learned while away on military training.<br><br>Take the needles that are in you PSK or sewing kit and run them repeatedly in one direction along a powerful magnet. Now you have magnetized needles that can be used to make an improvised compass. <br><br>Make the compass by floating the needles on a cork or leaf in a cup or small pool of water.<br><br>I used the magnets on the speakers in my car by opening the trunk. If anyone has tried this please let me know if it was successful.
