TESTING AN OBJECT TO KNOW IS THE OBJECT A CONDUCTOR OF ELECTRICITY OR NOT

Materials:
1bulb
Copper wire
1battery
1Scissors
Some objects [metal, wood etc]

INSTRUCTIONS
Built a circuit using bulb, battery, copper wire, scissors [for cutting] connect the battery to the wire, connect the other end to the bulb, connect one more wire to the other end of the bulb. Leave the end of the other wire open.Connect a wire to the battery but don't let the end of this wire touch the end of the wire connecting to the bulb. This will be the gap.

Now place your object in the gap of the wires.

If the bulb lights up this mean it is a conductor of electricity. If the bulb does not lights up it is not a good conductor of electricity.

CAUTION DO NOT TEST ANY LIQUID ITEM. USE 1.5 VOLTS BATTERY.
