How does static electricity build up and create a shock?
Quick Answer
Static electricity builds when electrons transfer between surfaces, leaving one object more negative and another more positive. A shock happens when the charge suddenly jumps through the air.
The Full Story
Static electricity is usually caused by contact and rubbing between materials, which can transfer electrons from one surface to another. The imbalance of charge can stay on an object until it finds a path to discharge. When the electric field becomes strong enough, the charge jumps through the air as a spark or shock. This often happens on dry days because dry air does not leak charge away as easily. The effect is common in balloons, clothing, carpets, and doorknobs.
