Cut the copper wire. You need two strands about 1.5 feet (0.4572 m) long.
- Use small wire cable cutters to cut the copper wire.
Remove 1″ (2.54 cm) of shielding from the ends of both strands.
- The shielding is the plastic that covers the copper wire. Removing it can be achieved by carefully squeezing the cable cutter so that it cuts through the shielding but not the wire. The shielding can them be stripped from the ends with your hands.
Use the nail to pierce two holes into the cork. The holes should be in the middle of the cork about 1″ (2.54 cm) apart.
Hold the two copper strands parallel to each other in the air.
Place one end of each strand 2″ (5cm) inside the two holes drilled into the cork.
Bend the end of the two strands inside the cork into a hook shape. The hook of each strand should curve the same way.
Cut the iron wire into 1-1/2 to 2 inch (3.8cm to 5cm) strips. Make five strips.
Twist the five iron wire lengths together with your fingers.
Place the twisted iron wires onto the copper hooks, making sure it touches both copper strands.
Put the cork stopper into the glass jar.
Take one strand of the copper wire not in the glass jar and wrap the end around one end of the battery. Repeat this for the other strand of copper wire and the other end of the battery.
