Step 1: Cardboard!!!
Hot glue gun
Two bags of glue sticks
Gorilla tape is also a must!!
Along with spray paint (black)
Also chemical lights (get blue and green ones)
Find tubing from a hardware store, the stuff I found was for organizing cables behind a TV.
Step 2: "Doe Ray Egon!!"
But definitely go here http://www.gbfans.com/
I cut out two shapes out for the body. Then I glue them on top of each other and gorilla taped the edges.
BAM proton back backing done.
*Pat yourself on the back*
Step 3: "Ray I think he can hear you . . . "
Measure out the holes as there is actually an order to them.
Depending on the plastic it's either gonna be hard or easy to cut out the holes. I ended up having to use my glue gun end to melt away the edges and smooth out the circles.
For the red areas I found four plastic military flash light lens. Worked great. But anything transparent enough and red will work also.
*feel ashamed of yourself cause you probably ripped the plastic cover from some little child hands as it was the last one*
