Make a Compass

How to Make your own Compass

You will need:
a sewing needle
a small dish of water
a magnet
a piece of cork (get an adult to cut a circle off the end of a wine bottle)

Place the round piece of cork on the water in the dish. Then rub the magnet over one end of the pin, but always rub in the same direction. Do this for one minute.
Then place the pin on top of the magnet. The end of the pin that your rubbed, will spin the cork around in the water, until it is pointing North.

Where are South, East and West?
Why do you need to rub the needle with a magnet?
