Introduction: The MacGyver Flashlight

How to light a bulb with one wire and one battery.

Step 1: Obtain a Battery, an Electric Wire, and a Small Light Bulb

That's right. You only need one wire.

Step 2: Strip Both Ends of the 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.

Step 3: Twist the Ends of the Wire

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 twist the threads with your other hand to form a solid wire.

Step 4: Connect the Wire to the Battery

Hold one end of the wire to one of the battery terminals.

Step 5: Connect the Bulb to the Wire

Hold the other end of the wire to the threads on the side of the metal portion of the bulb.

Step 6: Complete the Circuit

Place the bottom tip of the bulb on the other terminal of the battery.
