The Orange Box: Portal Hints
How can I get this orb into its receptor device?
1 of 6: As with previous orb-into-receptor problems, there are two things you need to locate.
2 of 6: One is the spot where the orb bounces off a wall, and the other is the spot where the receptor is shining its dim red light.
3 of 6: It's easy enough to find the orb bounce spot, since you can watch the orb as it bounces. Also, it leaves the usual black mark on the wall.
4 of 6: As for the receptor, it's on the floor, so it's shining its red light up at the ceiling.
5 of 6: Fire a blue portal at the ceiling where the red light hits it, then fire an orange portal at the wall where the orb's black mark is.
6 of 6: Then just wait until the orb ends up in the receptor, after which it'll be out of your way.
