The goal of the chamber is to get one of the players to the area behind the glass walls. To do this the players must use Thermal Discouragement Beam to lift the Crusher, lift a platform from the Goo and then quickly lift the other crusher.
When the first Crusher is raised enough for you to go under it without risks, make your way on the first Piston Platform and place portals on the wall next to you and the other one a little higher on the opposite side of the same wall.
3
Aim the beam at the receptacle at the center.
When the platform appears on the opposite side, go through the portal.
4
Wait until the platform is one panel higher than the Crusher and then aim the Beam at the Catcher on the right.
5
Go under the Crusher as soon as it has been raised enough. Then proceed to the area behind the glass and fire the second portal to the panels next to the door.
6
Aim the Beam at the left Catcher again and go through the portal.
