Chell's Portal 2 potato GLaDOS

Why? Because you can't have a proper Portal 2 cosplay without your friend GLaDOS!

I knew the convention was going to be very crowded and some parts of the portal gun were too thin or flimsy. I planned on having the gun checked in the cloakroom until the time of the contest (after that, I didn't care if something broke off). So I needed a prop to hold for the early hours of the convention, before heading out for the contest. This was such a fun project (and I'm calling it a project because up until it was finished, I still wasn't sure if I would take it with me) and also the first time I used LED for cosplay.

"How are you holding up? Because I'm a potato"

I took tin foil, shaped it into a potato and covered it with 3 layers of plaster bandage. The boring part was that I had to wait for each layer to dry before adding the next one. It took all night!

After the shape was to my liking, and solid enough, I sanded it to make it smooth, and punctured a hole to remove the tin foil. That hole was done on purpose, because it would be the place that the LED's batteries would go. 

Have a potato.

The metallic face was made by craft foam, carved with sculpting tools, and painted with acrylics. Added a clear plastic sheet, that I sanded to diffuse it and painted it yellow.

The wires were a combination of hollow plastic necklace chord and thin wire (both materials are mainly for jewellery making). The connecting parts (I'm sorry, I don't speak electrician) were craft foam, shaped, glued, and painted!

LEDs seem to work fine and the batteries fit perfectly into the hollow potato (thanks dad!)

This was a triumph! 

Unfortunately GLaDOS was one of the props that didn't make it. Her lights, literally, went out the night after the convention (must've pulled a wire on the drive home) and the rest of her is actually missing. Whereabouts unknown!
