Portal: Forbidden Testing Tracks - Part 4 (Obtained a New Gun, A Gel Gun!)

Continuing my Portal: Forbidden Testing Tracks journey once again, this time i've continued where i last left off, doing whatever i was doing at the beginning, eventually figured out what to do after a spending quite a long time of searching and messing around, and eventually i made it to the point where i got a new toy for me to play with, and that toy is a Paint or Gel Gun, i will say it's a Gel Gun since they're called Gels in the Portal Universe, anyways..the gel gun is self-explanatory, it shoots out gel, so yeah, enjoy this Portal 2 mod video!
