- A magnet
- A glass container
- Safety pin
WHAT TO DO
First, bring the safety pin on the magnet. Then, pour some water into the jug and drop the safety pin in it. Place the magnet on the outside of the jug, on the side of the safety pin.
When this is done, the safety pin follows the direction of the magnet, until it is above the level of the water.
WHY THIS HAPPENS
This happens because the force of the magnet also works through the glass of the water. If the jug was made of iron or steel, the safety pin would still come up, but with a lesser intensity, as the magnetic force would be absorbed by the sides of the jug.
Use different variants of magnets, as well as different surfaces, such as a steel vessel or a vase and you will see how magnets react differently on different surfaces.
