If you put six dominoes in a line, flat and end to end, you can do an experiment to see how electricity moves along a wire. Each domino must touch the next one. Draw  back the lead domino and tap it sharply against the next in line. Watch what happens. Each domino moves just a little, except for the end one, which shoots away. The  electrons in a wire move in the same way. When one end is 'pushed' by an electrical force, each electron in the Wire moves just a little, but together they send a fast and  powerful signal along the wire.
