You would need a piece of cork or other soft floating material, perhaps polystyrene, also a needle and a magnet. stroke the needle with the magnet a few times in the same direction and them insert the needle into the floater so that it is horizontal when the floater is placed in water, place floater into a container of water, the needle will point toward the magnetic north.
We need compass to know the direction we are going.

The oldest compass in the world is believed to be the Han Dynasty compass, which dates back to around the 2nd century BC in China. This compass was made of lodestone and consisted of a magnetic spoon floating in a dish.
To find the north side of a magnet without a compass, you can use the floating needle method. Rub a needle on a magnet and place it on a small piece of paper floating in water. The needle will align itself with the Earth's magnetic field, pointing north.
well the first person to make the compass was the chinese.
The Chinese invented the compass during the Han Dynasty, around 206 BCE to 220 CE. The compass originally consisted of a lodestone spoon floating in a bowl of water and was used for divination rather than navigation.
You need to draw this \______/ floating on water to show a floating boat.

A lensatic compass has a sighting lens and a floating dial for precise navigation, while a mirror compass has a mirror for sighting and a fixed dial for general direction. Lensatic compasses are more accurate but require more skill to use, while mirror compasses are easier to read but less precise.
