About 300 years ago, Stephen Gray an astronomer, held an experiment to do with electricity. He made a very important discovery. He placed a boy on 2 swings, held by a wooden frame with silk rope. He had a Hauksbee machine that generated static electricity. He generated the electricity which charged through the boy, using a connecting rod. The boy had a plate of gold leaf in front of him, and when the electricity was generated the gold leaves rose to his fingers. That’s when Stephen Gray made the discovery that electricity passes through some things and some things hold the electricity inside them. These are called insulators and conductors. Insulators hold the electricity or electric chage and the conductors let it flow within them. The silk ropes were insulators whereas the boy was a conductor. This knowledge is still used today with electricity towers. Certain things need the electricity to flow through them and some things need to stop it.
I understand that this was a very important discovery in history and that we may not have very important things like electricity lines and towers if it was never made. I wonder how this would actually effect our lives? I know that we might not have electricity but what other things could this seriously effect? Also, how would it feel to have electricity charged through you so that you could do what the boy did?
