This video was mainly about Steven Grey and the discovery he made about Static and Current electricity, how Steven Grey found out about it, and how static and current electricity works.
Electricity can move through humans and other materials such as metal.
Materials like silk, hair and glass are insulators.
The way electrics pylons work was discovered by swings suspended from wooden planks by silk ropes.
Did the wooden frame effect the outcome of what happened to the boy?
How does the other machine work?
I can tell this was an important discovery for our everyday lives.
