Burgmoud: For those thinking this is something new, sorry to burst your bubble, but its not. Its been around since the release of Portal 1. Its not a cheat either, just using a function of the game to your advantage.

There was no glass in Portal only the glass you need to break i tred there and it did not work

I discovered this a long time ago,it's cool.

@pepeleprawn while creating portal maps i found a tutorial on how to prevent this type of thing.

Wow, cool. where did you learn that?

Yes.

I included portal bumping in one of my maps:

Good illustration/tutorial

That was neat.

CrazyGamer. well leave the crosshair alone and shoot both a blu portal and a red portal in the same place and the second portal you shoot will bump behind the glass. :D enjoy

Tryed so many times but still not working :/ someone can help ?

I also figured out that you can wait as long as you can as long as a portal is right on your side of the glass than just click blue/orange right between the portal and the glass

I will check it out! thanks.

hey KILLER 9639 I made a map representing your cheat!!!

Here you go: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=254744346

The number of people voting this up just shows how many n00bs are playing front page stuff and rating them. I don't know anyone that doesn't know about portal bumping.

Also, just put a light strip next to the panel or make one side non-portalable. You should have also mentioned that it works on grates, laser grilles, and fizzlers as well.

y are you so awesome

Yeah your stuff is really cool and interesting :D

but srsly thank you for taking intrest in my stuff :)
