Barbie Doll Electric Chair Science Fair Project!

Step 7 Now that we know how an electric chair works, let's set up the electrodes!

You will need to build three basic forms out of epoxy putty for this step. You can either use a colored one like I have (FastSteel) or paint over it later with silver. It's up to you! Also, if you have metalworking experience, feel free to use your skills here. You will end up with a much better looking product. I chose the epoxy putty because my boyfriend suggested it and it was the easiest solution. It's also not a conductor, which will help keep me from getting shocked! Yay!

In the next step we'll drill small holes in the putty to allow for wire connection.

Tips for working with epoxy putty:
- keep fingers moist, otherwise you'll end up a sticky mess.
- work will small amounts.
- fashion small pieces and build on them to avoid a piece drying in the middle of you molding it!
- check the dry times on your specific product and work fast!
- be careful when pulling the putty and the plastic wrap apart - make sure the epoxy is completely dry!

For the back of the chair, pictured in pictures 1 & 2:
- lay a sheet of plastic wrap over the back of the chair. This will keep the putty from sticking.
- form a flat piece that covers the top and sides.
- from the flat piece you will build a pipe-like piece big enough to fit your lightbulb inside - try to do it as shown in the picture, it makes it easier!
- also keep in mind that you need to make it thick enough that drilling won't break it.

For the helmet, shown in picture 3:
- cover Barbie's head with plastic wrap.
- place a glob of putty at the top of her head and work it down until the helmet is the size that you want.
- make sure to keep it thick enough to drill through!

For the electrode on the leg, shown in picture 4:
- roll a small piece of putty into a snake, and make sure that it goes completely around her leg.
- place on the leg and flatten.
- try to keep the edges as straight as possible and watch out for bumps!
- you don't have to worry about thickness as much on this one because we can drill right into her leg!

THIS IS AMAZING I WONDER IF YOU CUT THE PLASTIC WRAP WHEN YOUR DONE USING THE  PUTTY.
