One of the basics of electronics is knowing how an electrical current works. For this video, you will need a 1.2V battery, a lightbulb, and 2 copper wires. First, take the wires and attach one end of each wire to opposite sides of the battery. Have a friend hold the wires there, or tape the wires down. Then, take the unattached ends of the wires. Take one wire and touch it to the upper part of the base of the lightbulb. Take the other wire, and touch it to the bottom. The lightbulb should now glow!
