Use an Aerial Faith Plate to launch a turret
The third achievement/trophy you can get in Chapter 2, chamber 6 requires you to nab the turret that gets released in the trash pile. The turret acts differently and more random as it goes through the portals so sometimes it will make it out and sometimes it will head right for the water. When you get the turret to land on solid ground, grab it and take it back to the beginning of the chamber. Drop it on the kicker- or the faith plate as they are called- and the reward is yours.
