Portal 2 Hints
How can I get the gel runway made?
1 of 10: The propulsion gel tube is hanging over the floor in a spot near the base of the excursion funnel.
2 of 10: Look near it for a small side room with another big red button in it. It's the one that works the gel tube.
3 of 10: To get into its room, fire a blue portal onto the back wall through the round hole in the glass wall, then put an orange portal on the wall to the right of the glass wall.
4 of 10: Standing on the gel tube's big red button will drop gel straight down onto the floor. That's a good start, but you need the gel to go all the way to the top of the ramp.
5 of 10: Leave the button room and look under the gel tube to see that there's a portal-friendly section on the wall next to the blue dots that lead to the button.
6 of 10: What do you think would happen if an extended excursion funnel were going along directly underneath the tube when it was dropping gel?
7 of 10: To find out, you'll need to move your franken-turret from the funnel's big red button to the gel tube's big red button. (That's because you can't enter and exit the gel tube's button room while your portals are being used to extend the funnel.)
8 of 10: Stand on the funnel's big red button to activate it, then put an orange portal above it and a blue portal on the wall section under the gel tube.
9 of 10: Notice that the gel gets caught in the funnel and carried along. Also notice that it doesn't ever fall out of the funnel on its own.
10 of 10: Wait until there's a continuous stream of gel in the funnel that goes past the ramp, then relocate the blue portal somewhere to get all the gel to drop and make your runway.
