Barbie Doll Electric Chair Science Fair Project!

Step 9 Cut the wires and install them.

Four of the wires will be non-functioning and just to show the idea of a closed circuit. The two wires on the back of the chair are the most important and will supply power to the light bulb, so let's cover those first. You will need six pieces of wire for this part, so cut carefully. :)

Wiring the back of the chair as shown in pictures 1 &2:
- insert a wire into the top hole. This will wrap around the light bulb.
- curve it so that it fits the hole and around the light bulb.
- insert a second wire in the lower hole, this will make contact with the bottom of the light bulb.
- insert light bulb when both wires are in place.
- these wires will connect to the battery, so make sure they're long enough!

Wire the helmet to the back of the chair as shown in picture 3:
- these wires are just for show, and are only a couple of inches long.

Wire the side of the helmet to the leg electrode as shown in picture 4:
- yet again, these wires are just for show.
- make sure they're long enough to arc out away from the chair and Barbie's body.

Picture 5 shows the length of the "just for show" wires, for reference.
