what would you do if u had the portal gun in real life? also ask questions for what if scenarios, we got smasrt people on fourms... (yes i got inspiration from the forums on the wecreatestuff site)
You couldn't really do the looking in the locker room thing for one reason, You're not invisible and the portal is not invisible. Just sayin'. Anyways I would use it for easy travel. Tired? Just make a portal in the ground and make the other portal. further away from you. Repeat until you're at the place you want to be.
i would use the GUN for like lunch go home and eat and if like you forget something at home go get it or to poof on to rides at disney world (cause i hate the lines) And to poof around the world to see stuff but just think if terrorists had these GUNS we would be screwed up the but
