ELECTRONS FLOW SLOWLY, SO HOW CAN LIGHTS TURN ON INSTANTLY?

This question has an easy answer: the lights turn on instantly because wires are ALREADY packed full of movable electrons. So if the battery or generator tries to pull some electrons out of one end of a wire, it has to suck all the electrons forward. Or, imagine a drive belt with two pulleys: when you turn one pulley, the whole belt moves instantly, and the distant pulley turns too. Yet the belt itself didn’t move very fast. The electrons inside the wires are like the circular drive belt.
