📖 Read the story
Do you sometimes touch a door and feel a small shock? This is static electricity. Scientists know about it, but it is still a mystery. Static electricity happens when you rub two things together. This makes a tiny electric charge on the surface. A charge is like a small spark of energy. It stays in one place. When you touch a metal object, the energy moves very fast. Then, you feel a little ‘zap’! This is a surprise for many people. Scientists want to understand it better. They study why some materials, like carpets or balloons, make more sparks than others. They are working hard to learn new things about it. It is amazing that a simple thing like a shock is still hard to explain. Have you ever felt a zap after walking on a carpet? It is science in your house!
