Make Your Own Portal Gun!

It's not finished at this point.

Want to make your own Portal gun? Well then you’ll have to figure out science beyond the greatest minds alive. But if you’re too much of a thicko for that, you could instead make a replica. Stephen Granade, he behind last year’s mighty Rubik’s Companion Cube, now offers detailed instructions for making your very own reality-distorting weapon.

Granade tells us it’s made “out of PVC, spray paint, and a liberal amount of gee-whiz can-do attitude.” There’s also bits of old fabric conditioner bottles, clear plastic tubing, and steel rods. Clearly everyone needs to do this in the next two days, so it’s ready for Halloween.

He then goes on to point out how much fun portals can be for babies:

Awkward when it's time to stop.

Stephen, you are a hero to us all.

    Jesus fucking christ i’d kill myself out of sheer shock if I was that baby.

    And I could comprehend the idea of suicide, too

  2. Excalibur says:

    Neat, but it doesn’t look that good to me.

  3. Gladman says:

    Looks pretty sh*t quite honestly.

  4. James says:

    I’m not sure if it was covered in the Portal craft festival that was last December, but I also found this last night. Rather impressive as case mods go, I think.

  5. says:

    I like the Portal gun on Instructables better, but it’s a lot harder to make.

  6. Unimpressed says:

    What’s with the Blue Peter shit? Go scour the interwebs for more stolen stories that you can pretend you’ve had laying around for ages but haven’t gotten around to writing about yet.

  7. Idle Threats and Bad Poetry says:

    I think this post was worth it just for the baby picture.

    Now who’s gonna make a sentry?

  8. The Hammer says:


    That source of this article was published yesterday.

    Also: Kill-Joy.

    @ Unimpressed

    That comment was a little harsh and rather presumptious. I think you’re just trolling.

    Obvious troll is sneaky, or not?

  10. The Hammer says:

    Oh, I’d like to say how much I laughed at ZenArcade’s comment. I think I’d do the same if I was in that predicament!

    When a baby reaches terminal velocity, what is the maximum dispersion radius of baby-vomit?

  12. phuzz says:

    not just vomit, at that speed the nappy will fly off, and, well, just duck ok?

  13. KindredPhantom says:

    Haha more portal crazyness over a year after it’s release.

  14. terry says:

    I like Stephen Granade but he doesn’t half go off.

    I’ll get me coat.

  15. Weylund says:

    As any parent knows, baby vomit is not a mixture governed by the laws of physics. You’ll be putting on a clean pair of socks from your sock drawer after a long night of “baby with the flu”, and you will find trace amounts of baby vomit ON THEIR SOLES.

    You will also realize that there is probably urine on your hands.

    I love having kids.
