Portal 2 Hints
How can I get gel all the way up there?
1 of 6: Put the orange portal on the floor under the gel flow if it isn't already there.
2 of 6: Starting with a spot on the floor near the slanted surface, place blue portals so that the gel is spewed toward the two vertical support columns.
3 of 6: Once you get some gel onto the side of the left support column that faces the right support column, put a blue portal as high up on it as you can.
4 of 6: That'll get gel to splash across to the right support column.
5 of 6: After that happens, relocate the blue portal as high on that column as you can to get gel to splash back onto the left column in a higher spot.
6 of 6: Keep that back-and-forth up until there's gel on the right support column above its walkway.
