How to light a bulb with one wire and one battery.
That's right. You only need one wire.
Remove the insulation covering the metal portion of the wire with a knife or wire stripper to expose the ends of the wire about one cm long.
The copper threads in the wire may flair out and make it hard to handle. Grasp the wire in one hand toward the end of the insulation, then ...
Hold one end of the wire to one of the battery terminals.
Hold the other end of the wire to the threads on the side of the metal portion of the bulb.
Place the bottom tip of the bulb on the other terminal of the battery.
