Can you believe this Portal gun was built from scratch?

This Portal gun will really make [aNoodleJMC's] costume pop this year. He actually built the video game weapon replica from scratch. It even includes some electronics to light it up blue or orange depending on which portal he’s planning to fire at an available flat surface.

There’s a lot of parts that went into the project, but by far our favorite one on the list is an acrylic toilet plunger. Its handle serves as a light pipe for the colored LEDs and can be seen above as a cloudy rod at the center of the clear barrel. A 4″ and 3″ PVC pipe helped to form the rest of the barrel, along with a 3″ clear acrylic pipe for the transparent areas. The bulbous parts of the body were sculpted from florist’s foam. Once he had all of the parts roughed out it’s obvious that [aNoodleJMC] spent a ton of time filling problem areas with Bondo, sanding everything smooth, and giving it a paint job he can be proud of. We hope he didn’t forget to include GLaDOS in the fun.

We actually just bought our Portal gun. But that’s because we had the big plans of adding the ability to levitate objects.

  2. Not bad! I think I’ll build my own once I finish my 3D printer.

    Am I the only one who has no idea what Portal is? I’m guessing from the context that it’s a video game.

    I like the use of recliner arms :) Looks easy enough to replicate as well :)
