Portal 2 Hints
How can I use propulsion gel to jump the big gap?
1 of 12: Look on the other side of the starting area to see a gel tube in the ceiling and a button pedestal on a high-up ledge.
2 of 12: There's a portal-friendly bit of ceiling above the ledge, so put a blue portal on it, then put an orange portal on any portal-friendly wall that you can reach.
3 of 12: After dropping onto the ledge, press the button on the pedestal to verify that it causes orange propulsion gel to come out of the gel tube.
4 of 12: Now you need to spread some of that gel onto the ramp.
5 of 12: Remember how you spread repulsion gel around in several of the alpha spheres' test chambers?
6 of 12: The floor underneath this gel tube is portal-friendly, so put an orange portal on it.
7 of 12: Put a blue portal on a spot on the portal-friendly wall that's near the ramp, then press the pedestal's button.
8 of 12: If the ramp doesn't get completely covered in propulsion gel, move the blue portal accordingly and press the button again.
9 of 12: To make sure you can get across the gap, you should also get some propulsion gel splattered onto the floor next to the bottom of the ramp.
10 of 12: TIP: To quickly get the ramp and most of the floor leading up to it covered in gel, put the blue portal on the portal-friendly wall surface that's directly across the room from the ramp.
11 of 12: When that's done, quicksave, then drop down to the floor and move to where you can make a straight run at the ramp.
12 of 12: If you got enough propulsion gel on the floor and ramp, you'll be able to run up the ramp and across to the lower of the two areas on the other side of the gap. If you fall into the toxic lake, quickrestore and spread some more gel around, then try again.
