   The batteries make the power that travels through a metal piece of wire and touches the end of the bulb.The bulb lights up and reflectors reflect the light.Of course,electricity has to go back to the beginning in a series cicuit so after the metal piece touches the bulb it goes back round to the spring at the beggining that is touching the batteries.But in the middle there is a switch.When the switch is off the metal is not connected and so there is a break in the cicuit but when you push the switch forward and on; the metal connects and the bulb lights up.

   The plastic casing around the outside is not a conductor; it’s an insulator.It will stop the electricity from flowing into your hand and eletricuiting you.
   I learnt this all in the very useful lesson. 🙂 B) 😀
