  • Question
    What if I do not have any of the supplies?
    Community Answer
    Remember that the sun rises in the east and goes down in the west. So if the sun is going down on your left, north is ahead of you and south is behind you. If it's coming up on your left, north is behind you and south is ahead of you.
  • Question
    How is the leaf used, and how is the needle passed through the leaf?
    Community Answer
    Set the needle on top of a floating leaf. The needle will turn the leaf with it.
  • Question
    How can I make this compass if it is night and I can't find the Little Dipper?
    Community Answer
    Wait for morning. Night navigation in a survival situation is inadvisable. Focus on fire and shelter instead. The magnetic field will still be there in the morning, but it won't matter if you're not.
  • Question
    Is there another way to make a compass?
    Community Answer
    Yes, you could try the string and stick 'Chinese' method, which allows you to skip using water or oil. The thread 'floats' the hanging needle. Positions can still be marked if the stick or pencil is set over a cup or ring.
  • Question
    Can you use a bottle cap instead of a cork?
    Community Answer
    Yes. You can use anything you want that floats, as long as it can hold the needle without it falling into the water.
  • Question
    What should I do if I need to take it somewhere as a project for school?
    Community Answer
    Keep the compass and a magnet inside of the bowl, and carefully take it to school. Refill the bowl with water in a sink.
  • Question
    How does it point in that direction?

    The earth has a north and south pole with an electromagnetic force emanating from them. This force is so great that it causes any compass to turn towards the origin of those forces.
  • Question
    Do I need a magnetizer?
    Community Answer
    Yes, it is vital to use a magnetizer.
  • Question
    Why would I use metal instead of anything else?

    Community Answer
    Metal is a conductor of electricity, which is similar to magnetic fields and poles. If you use something else like plastic, it will not turn in the right direction towards the poles since it is not magnetic.
  • Question
    What if a needle is not magnetized?
    Community Answer
    Then it won't point north.
  • Question
    Say I want to make a professional looking compass, like one that I could find in a store. Could this method still work, but instead of using a bowl I would be using a casing for the compass?
    Community Answer
    The basic method is the same, yes.
  • Question
    What if the cork does not stay still?
    Community Answer
    Try using different materials, or maybe making the cork thicker or thinner.
  • Question
    How do I know which way is north and south?
    Community Answer
    The floating needle turns towards north, and you can work south, east and west from there.
  • Question
    Are there any substitutes for cork?

    Yes. You can use anything that can float and be easily moved, such as a piece of foam.
