The Orange Box: Portal Hints
How can I get this orb into its receptor?
1 of 8: As in the previous chamber, notice that the orb leaves a black mark on the wall it bounces off of.
2 of 8: So fire a blue portal at the black mark.
3 of 8: It's not so simple this time. The orb will go through your blue portal and then start bouncing off of another wall.
4 of 8: Find the receptor device a bit farther down that same wall.
5 of 8: Then find the spot on the left wall where the receptor is shining its red light.
6 of 8: That's where you need to open your next portal.
7 of 8: When the energy orb is going left-to-right in front of you, fire your portal gun at the red-lit spot on the left wall.
8 of 8: Then just wait for the orb to reach the receptor device and power the nearby moving platform.
