A small test i made in Portal 2 authoring tools. I believe that this form of vent was scrapped from the actual game. If you want to learn how to make a Diversity Vent click this link: http://developer.valvesoftware.com/wiki/Diversity_Vent
Also, please excuse the fact that the video plays twice. I have no idea why that happened. :S

@stormtroopers199 This isn't G-mod. Its Portal 2 authoring tools beta, you can use it to create your own portal 2 maps. Its kinda modding the source sdk. :)
