Create a Aperture Science Personality Construct prop from the game Portal 2. Easily made out of paper maché!
To make this prop you’re going to need a large bowl to shape it, newspaper, glue/water mixture, aluminum foil, scissors, white or light gray spray paint, some kind of glue (I would advise rubber cement, mod podge, or both.), a hot glue gun, an optic print out, and something to use for the handles (I used pieces of a thick wire hanger), and thin cardboard.
You may also want masking tape, black duct tape, acrylic paint (black and white), transparency paper, and sandpaper.
I hope this guide is both interesting and informative. :) I made Wheatley, but you could also make any of the other cores in the same way.
