How to make compass : The floating needle will behave like a compass, with one end always pointing to magnetic north. A story is told that this is the same type of compass used by Christopher Columbus. Since the metal needle of the time were poor, Columbus had a lodestone to remagnetize his floating needle.

A bar magnet will affect the floating needle in the same way it did the compass. By moving the bar magnet under the dish, the children can discover that magnetism goes through water.
