Portal 2 Hints

How can I keep the exit door open so I can go through it?

  • 1 of 7: If you'll remember what you learned in earlier test chambers, you'll realize that you need to put a weighted object like a storage cube on the button to hold it down.
  • 2 of 7: Looking across to the exit door's floor, you'll see that there's a button pedestal over there.
  • 3 of 7: There doesn't seem to be any way to get across to that floor, but remember that repulsion gel will bounce you with an approximately equal and opposite force.
  • 4 of 7: Run off the button's floor so that you fall into the gel pit, and you should be bounced out of it and onto the exit door's floor. (Leaning on the "Move Forward" key throughout the process may help.)
  • 5 of 7: Press the pedestal's button to get a storage cube to drop into the gel pit and get bounced onto the starting floor section.
  • 6 of 7: Drop down to that floor section, then pick up the cube and return to the big red button's floor.
  • 7 of 7: Drop the cube on the button, then bounce back over to the exit door's ledge.
