How do you make a homemade light bulb?

Answer 1

• Place the cork stopper on top of the jar. Make two holes through the cork by pushing the nail into it. Push the copper wire through the holes until 2 inches of wire stick out from the underside of the cork stopper inside the jar.

• Step 2

  Remove the cork stopper from the jar and fold the ends of the wires to form hooks.

• Step 3

  Twist a few strands of the picture hanging wire together. Place them in the gap between the hooks of the copper wires to form the filament.

• Step 4

  Place the cork stopper back on top of the jar. The wire elements and the filament will be inside the jar, with the wire to be hooked up to the battery outside it.

• Step 5

  Wrap the wire ends around the contacts on the dry cell battery. The bulb should light up.
