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:
Stephen, you are a hero to us all.
