This is some pretty amazing editing and 3D and CGI work: http://youtu.be/AsdEXlPsobI
Basically, what would happen in real life if portal guns existed
Wow, that was fantastic!
I love how these "Portal gun in real life" videos always end up at some point having buddy #1 being a total douche to buddy #2. ;D
That's how mutliplayer Portal 2 could have ended if they didn't make it so darn cute
You still drop your friend in acidic goo though lol
