Well let's see... When i was trying to figure out how traffic lights worked i came out with this: Whe looking at them changing the colors i would never of thought it would be eletrical wires and stuff in there. I thought that little men that are very very small held up the colors green red and yellow to change the colors on them. I even asked my dad if that was true and of course he said no and that is rediculus.I ignored that and still thinking about it. At night time i saw the red light always flashing and never changing a different color. So than i thought sinc eit was late and the little men were tired, they were drinking coffee or what ever i thought back than and there were flashing the red colored sign back and froth to tried to go to a different color. So than since i'm older now ( 14 ) i now know how they work \
