How to make a switch with simple methods?
Things required:
        Small piece of wood or cardboard
        Two metal thumbtacks
        Large metal paperclip
    Three pieces of wire
    Bulb and bulb holder
    Battery and battery holder

Procedure:
    Insert the battery and bulb into their holders.
    Connect one wire between the bulb holder and one end of the battery holder.
    Connect another wire to the other end of the battery.
    If you are making your own switch, lay the paperclip on the cardboard or wood, push a thumbtack through it, securing it to the board, and push the other thumbtack into the board across from the first so that the paperclip can be rotated to touch both, creating a metal path for electricity to travel.
    Wrap the other end of the wire on the battery holder to one side of your switch.
    Connect the last wire between the switch and the bulb holder.
    Light the bulb by closing the switch so the electricity can flow through an unbroken current.
