Hurrah, we come to the end of the module! We started the module wondering how we sometimes get small electric shocks even if there is no wire carrying electricity.
Especially if the weather is dry, and there is friction, our body gets charged if we touch some object. If we then touch a different object, charges flow between our body and the other object.
So, we ourselves create a small electric current. As this electric current moves through our body, we experience a tiny electric shock!
