First, I will show three simple experiments that they can easily do at home:
1- Rub two balloons on my hair. When I close them, they repel each other
2- Rub a balloon on my hair. Then roll a soda can toward the balloon.
3- This time, I will rub a balloon through my hair, and then try to bend a stream of water using it to different directions
Now that they are excited, I will start explaining the reason. I will give a simple introduction about the positive and negative charges. Then I will draw how the charges are placed on the balloon, and how they redistribute the charges on nearby objects.
