While builders are finishing the FOUNDATION, SKELETON, CONNECTIONS, and CLADDING, other workers move to the inside of the building to start installing the ELECTRICITY.
Electricity is very important in a modern skyscraper, for lights, computers, and many other machines. Electrical wires run everywhere, but they are hidden in walls, ceilings, and floors. They are like the hidden nerves inside our bodies. Electricity makes the building light up so people inside can see, like our EYES help us to see!
