INSULATOR…….

Insulators is a element that CAN’T flow energy through itself. And these are insulators: Air, Vinegar, Bottle water, Rubber, plastic, cloth, CD, paper, electric tape, wood, cork.

CONDUCTORS…..

A Conductor is a material that CAN flow through itself. And these are conductors: Steal, Salt water, Graphite, Titanium, Brass, copper, Aluminum, Ruler, cobalt bolt, Gold.

My circuit tester took me two days to build my wires are five inches long and it has alligator clips and when it has power (like a battery) the light bulb lights up.This is my circuit tester. I labeled it so you can see where everything is.I noticed that most conductors are metal. But one conductors are NOT a solid, Salt Water. I think the salt water worked because the minerals in side it. And when I put my circuit tester in the salt water the light bulb was barely working.
