Walkthrough
- Jump in the Excursion Funnel and fire a portal on the ceiling.
- Wait until you've reached the second area and when possible, place the other portal on the wall next to the windows.
- You should enter the portal and head for the Frankenturret. When it is in your reach, pick it up.
- Go stand between the Funnel and the wall closest to it. Shoot a portal from the wall to the floor in the area below. Look for small panels with grey and white colours.
- Place the Frankenturret in the Funnel and wait for it to reach the button.

Test Chamber 01
The first chamber to introduce Excursion Funnels, the player needs to use the Funnel to reach a Frankenturret and direct it onto a Button located on the ceiling. Originally made by GLaDOS, Wheatley defends the idea he made it by adding the word 'TEST' to the wall with white panels, saying "Not entirely, not entirely. Look at the word 'test', on the wall there. That's brand new."
