The Cutting Edge Of Navigation

You can improvise a compass by taking a razorblade OR needle (any piece of ferrous metal actually) and magnetize it by using a magnet: The magnets in your telephones headset can be used just to mention one possibility
Move the magnet over the razor/needle with 30-40 steady strokes going in the same direction. 
The strokes starting/end point will later be the South and North direction of the compass.


I attach the razor to a piece of cork.

And let it float in a plastic cup: It points immediately to North.
