Portal 2 Chapter 8 Test Chamber 16

This is the fifty-sixth level of the game, and takes place within an incomplete Aperture Science Test Chamber. This level features both the Excursion Funnel and Repulsion Gel, and demonstrates the way in which the Gel can be used to dispose of some threats. Turrets are present as an additional hazard in this level.

Test Chamber 16
This was the last actual test within Wheatley's test tracks. The chamber primarily utilizes Repulsion Gel, which are used to rid the Turrets that were an obstacle to the exit.

If one of the turrets are saved from the gel, it can be used to fire at Wheatley's broadcast monitor screens. Destroying this monitor, as well as every other monitor in the stolen tests (for a grand total of 11) earns the player the "Smash TV" achievement.
