This was a prop that I made for Halloween in the eighth grade (2012). after I played the game Portal 2 countless number of times, Inside there are two switches one to turn on the power and one to switch between blue and orange lights. Sadly during the process of building this portal gun my Ipod that I was using at the time of building this mater piece had split in half and all my data was lost on it. Here are the surviving photos from the build and I am still considering refurbishing my prop that is currently in the garage! It was sculpted with clay and paper mache with abs tubing in the middle as a support.
