With a little bit of help from Aperture Laboratories, these guys created a real Portal gun.

I've played all the Portal content and yet I'm pretty sure it would take me less than a minute to kill myself if I had one IRL.

I'm surprised there isn't a real Portal movie in the works. If they can make a film out of Battleship, this should be a piece of cake.

I like in the description he's like, if I knew it'd actually turn out good I wish we would have done more of a story with it. They did a pretty good job on this.

This is pretty stellar.

You could give someone a circular path by putting a portal in the floor and one in the wall, positioned such that when you fell through the floor, you'd fly out the wall, arc down and fall through the floor again. Subjectively you'd seem to be going in a circle rather than a straight line, and your velocity would be lower.
posted by George_Spiggott at 3:55 PM on June 12, 2012


I don't think that would work, because if you lose velocity, the next time through you won't have the momentum to make it to the floor portal. (At least with the game physics, which I think are fairly reasonable.) You'd have to have the gun and re-shoot the floor portal every time.

You know, it's just occurred to me - would you reach terminal velocity? Or normal terminal velocity for a human in atmosphere, anyway? The average person is big enough that they're going to make a lot of air move with them, and that air is also going through the portals. Indeed, the air coming through the top portal is going to push on the air below it, sending it faster through the bottom portal and creating a positive feedback loop. I suspect the limiting factor here is going to be either the turbulence at the edge of the air column slowing it down, or relativity.

Hi I'm on Metafilter and I could overthink a portal of beans.

Okay Metafilter, we need to figure something out: When the guy is falling at terminal velocity in the floor/ceiling portal configuration, did they get the sound right?

The way that they edited it, the guy's voice is choppy and changes in pitch rapidly, presumably due to some imagined Doppler effect.

I think applying the Doppler effect is correct, but it seems like the chopping is not. I think that sound would just travel through the portals. Rather than the low-pitched "moving away" yell being instantly cut off and a high-pitched "moving towards" yell starting, they would just mix together. In fact, in seems to me that you would hear a combination of his yell propagating directly from him to the microphone, his yell that went "down" through the portal (higher pitched), his yell that went "up" through the portal (lower pitched), along with some decaying echoes of those three sounds that would keep looping through the portals, just like he is.

On preview, ZsigE brings up an interesting point. If the air column itself starts to pick up some significant speed relative to the house, I'm not sure how that would affect the sound as perceived from the house.

Hi I'm on Metafilter and I could overthink a portal of beans.

Wait a minute. What if the portals are at either end of a constant-speed conveyor belt and there's a jet plane on it, with free wheels, trying to take off?

Portal Loop with a little bit of help from Ikea.

Awesome until the last moment. There's ways of saving that guy that don't leave him dead or with several broken bones, but that's not one of them.

That final blue exit portal is much too high on the house. Even without considering all the other momentum the guy has, he's basically falling out of a second story window!

But worse, if you look at how high he fell from, he should have flown horizontally much, much farther (he'd have gone farther than that if he was moving back up against gravity). He ought to have been a horrible splatter against that fence.

When he made that blue portal, I assumed he was dumping the guy into a lake or pool that was off screen. When he just fell in some bushes--and got up again, apparently fine--I was really disappointed.

I understand why this guy painted the whole inside of his house with moon rock-based paint, but I'm having a hard time figuring out why he did the same for his roof. Foresight, I guess.

I suspect the limiting factor here is going to be either the turbulence at the edge of the air column slowing it down, or relativity.

It depends on if you're going with a frictionless conveyor belt or not.

@ZsigE: I suspect the limiting factor here is going to be either the turbulence at the edge of the air column slowing it down, or relativity.

I forgot who - maybe Larry Niven - suggested that this kind of technology would have major implications. At the least, you could get free energy out of it: a continuous waterfall. Or you could use it as a railgun: set the thing up in an evacuated vertical cylinder - so no terminal velocity - and use it to accelerate a projectile before opening another portal to fire it. Or at worst, it could destroy the Earth: use the same railgun setup and don't release the projectile, and in not long it'll be falling at relativistic speeds, and bad things will happen whether you release it or not.

Wait. Wouldn't he eventually "burn up on re-entry" if allowed to continue the ceiling-floor loop long enough?
posted by sourwookie at 9:46 PM on June 13, 2012


Sourwookie, that depends on the answer to the question above about terminal velocity. Air resistance might put an upper limit on his speed which could be below what it takes for friction to hurt him that much. Or maybe the air is moving through the portal loop with him, in which case it won't slow down his acceleration, but neither will there be any air friction to hurt him.

But you made me realize the biggest problem with this video. They take much too long to rescue him from the loop.

He falls through the portal loop for 56 seconds. Which means that when he flies up out of the portal in the ground outside, he's moving fast enough to fly up for (almost) 56 seconds. That's enough to fly about 9,000 feet into the air! The world's tallest building is only 2700 ft tall.

In the video, he unaccountably only flies upward for a couple seconds, reaching an apogee of maybe a few hundred feet.
