what's that?what does that do?what about that one?
That light is a circuit . There are wires inside to help the electricity go from one place to another. The wires are conductors, a material that easily lets electricity go through it. The plastic around the wires are insulators, they don't allow the electricity to go through, witch keeps you safe from being shocked. the electricity runs in a circle to the light then to the switch. when you turn of the lights the circle is cut and the electricity can not continue it's path.
So that's how the light works. any more questions?oh right your on sleeping gas.
