Portal 2 Hints
How can I use light bridges to get a storage cube?
1 of 12: To start with, notice that one end of the light bridge is against a portal-friendly extended wall section. (NOTE: You can go into the small area behind the extended wall section to find more mysterious scribblings.)
2 of 12: What if you put an orange portal on that wall section, and then put a blue portal on some other portal-friendly surface?
3 of 12: Try putting the blue portal in several different spots to see how you can "extend" the light bridge to provide paths across the large pit full of toxic liquid.
4 of 12: Looking across to the other side of the chamber, you'll see both a button pedestal and a portal-friendly wall section near the exit door.
5 of 12: Put your blue portal on that wall section, then either go through the orange portal or walk across the extended light bridge.
6 of 12: Press the pedestal's button to get the nearby cube tube to start dropping storage cubes. (Note that it'll never run out of cubes, so there's no rush in getting one.)
7 of 12: Get on the light bridge and examine the cube-dropping area. You'll see that the only way to get into it is to go all the way around using the side passage that starts to the right of it.
8 of 12: Looking directly across the chamber from the side passage, you'll see a large portal-friendly wall section.
9 of 12: After returning to the floor near the extended wall panel, relocate the blue portal to the lower right part of that wall section.
10 of 12: Go through the orange portal and along to the end of the extended light bridge, then turn left. As you can see, there are a couple more turns between you and the storage cubes.
11 of 12: Go down to the end of the extended light bridge and grab a cube. (Depending on exactly where you set the blue portal, you may have to catch a cube as it falls by you, or it may land on the light bridge.)
12 of 12: NOTE: To get back out of the cube-dropping area, all you have to do is walk through the blue portal.
