Unused elements

These chambers are a tutorial/introduction to three test elements that Valve created, but didn't use in the game. The test elements shown are the Pneumatic Diversity Vent, Paint Fizzlers and Reflection Gel.

Carl Kenner's style mod was used to allow the use of the fizzlers and gel in the PTI.

BEEmod was used to add the vents as well as the doors, crushers and other minor items.

Crushers are usually more intimidating than a threat; that was true here also. Liked "cleaning up" the turret mess... the vacuum creates some nice mexhanix too.

They were going to add Reflection Gel as a new test element in the Peer Review DLC (it was also going to be able to reflect light bridges and funnels too), but after adding it Valve couldn't find a good puzzle / use for it. Reflection Gel was just left in during the update.

Wait..if both of the gel was unused. Why did they bother changing it? There has to be a reason.

Reflection Gel is Sticky Gel, it has all the same properties. It is able to counteract the slipperyness of Propulsion Gel-covered cubes.

Due to some limitations in the PeTI, you can only have one extra custom gel type in the list. Reflection and Sticky/Adhesion gel are actually the same gel anyway - with the Peer Review update, Sticky gel was replaced by Reflection Gel.
