Here are some W.I.P pictures I took while making my Portal gun . This is sort of a tutorial, I hope any of this will help you construct your own Portal gun!
1.) I cut the shapes out for the white parts of the gun from EVA foam, I sorta just guessed how big and what shape they would be from looking at the original gun. I then took a dremel and sanded the edges down. Afterwords I used a heat gun to heat the foam and form it.
2.) The claws are made from plastic, screws and EVA foam. I took an old plastic bin container and cut the shapes for the claws then screwed in screws at one joint so the claws could be repositioned. The tip was made from EVA foam, sanded and then sprayed black later on.
3.) The base/ barrel is complete constructed from PVC pipes and EVA foam. I believe I used two 4 inch couplings and two 2 inch couplings. The foam was cut and then sanded.
4.) Sprayed it all black now. The center plastic part is made out of a clear plastic tubing I got from Lowes, I sanded it down because sanded plastic reflects light better then regular plastic, it also gave it a fluorescent light look. The outer plastic part I actually took a large plastic cylinder container and cut out a piece of it to fit in the gun.
5.) I attached the now sprayed parts from the first picture. I also did some detail work and painted on the logo, aperture science barcode ad black line going down the largest white shell. I made ports for the wires out of thin craft foam.
6.) No pics of this but the wires I got from Lowes and cut them to the length I needed them and with E6000 glue (Used for almost everything in this, along with hot glue) I glued them into place. I also glued down the claws.
7.) To make the gun light up I bought four mini LED flashlights, they’re a dollar each at Target. I painted the tips of them with metallic blue and orange paint, metallic paint isn’t as thick as acrylic so the light shines through father nicely, the orange was a little dull so I took orange shiny orgami paper and wrapped it around the end of the flashlight to help the light be more vibrant. They are glued into place and fitted into a circle piece of foam which sits in the gun. It is removable so you can change the batteries when needed. Multiple flash lights for brighter light!

And tah dah! The gun is done! All in all it cost me maybe 40 bucks.
