Portal 2 Hints
How can I get repulsion gel onto that floor section?
1 of 6: Try putting a blue portal on that floor section and an orange portal under the lower floor's repulsion gel leak. (Note that you can't put a portal under the upper floor's gel leak.)
2 of 6: Unfortunately, that just splatters repulsion gel on the ceiling. That's not going to help.
3 of 6: You need to be able to put the blue portal on the ceiling so that the repulsion gel will drop down onto the floor.
4 of 6: Since the ceiling isn't portal-friendly, you'll need to make it so.
5 of 6: Move the orange portal so that it's under the conversion gel leak. That'll get the ceiling above the floor section painted white.
6 of 6: Now move the blue portal onto the ceiling and the orange portal under the repulsion gel leak.
