Answers
Answer:
Metal sewing needle
A magnet (It can be a flat refrigerator magnet or a more powerful magnet, such as a rare earth magnet—the most common type is made of neodymium—which can be purchased at many hardware stores. A stronger magnet will work best.)
A pair of pliers
A cork
Scissors for cutting the corkA wide cup, drinking glass or bowl
Water
PROCEDURE
Rub the magnet against the sewing needle at least five times. (If you are using a weaker magnet, such as a flat refrigerator magnet, rub the needle at least a dozen times.) Always rub the magnet in the same direction against the needle. Your needle should now be magnetized.
Now cut off about one quarter inch of the cork from one of the ends, making a small cork disk that is about one-quarter-inch tall.
Laying the cork disk on a flat surface, carefully push the needle through the side of the disk by using the pair of pliers. Push the needle all the way through the disk so that about the same amount of needle shows on either side of the disk.
Fill a wide cup, drinking glass or bowl with at least one inch of water.
Put the cork disk (with the needle) on the water in the cup. Try to keep the disk floating in the center of the water, away from the sides of the cup. What does the needle do? When it stops moving, what direction does it point toward?
