In the cold winter, children will find an interesting phenomenon, that is, when wearing sweaters, we always can hear the crackling sound and see the small sparks, that is because there is tiny electrical in our bodies that make us feel, think, and move. Have you ever felt a slight shock when you shook hands with other people? That's because we all have the power to generate static electricity! Today, Alpha Science Classroom is working with children to learn the secrets of electrostatic electricity and help them become the most powerful electricity through a simple children's science experiment.

  • Balloon

  • Empty soda can

  • An object made out of wool (such as a sweater, scarf, blanket, or ball of yarn)

  • Stopwatch

 Alpha science classroom:How to make a DIY Electrostatic soda can

1.Make sure the can is empty and dry, then blow up the balloon.

2.Hold the balloon and rub it with the wool object in one direction at a time. Repeat this step several times, accumulating static electricity on the balloon.

3.Place the sides of the soda cans on a clean table and bring the balloons close to the cans, but don't let them touch.

4.The can will begin to roll to the balloon.

Alpha science classroom: The theory of DIY Electrostatic soda can

When you rub the balloon on your hair, some of the electrons in your hair will jump onto the balloon. This leaves your hair with more protons than electrons, and therefore an overall positive charge. Similarly, the balloon now has too many electrons, and so has a negative charge. These opposite charges attract, which is why we see your hair stand up, trying to get close to the balloon. When we put the charged up balloon near the soft drink can, there are two results.

First, the negative charges on the balloon move as far away from the can as possible: similar charges repel! Secondly, the negative charges on the can move as close to the positive charges on the balloon as they can get, which creating an attractive force that moves the can along the table towards the balloon.

Is the DIY Electrostatic Soda Can of the Alpha Science Classroom very interesting? Children will learn the simple physical science experiment? Is it amazing?
