*Fire a portal at the end of the [[Excursion Funnel]] and the other portal at the end of the [[Turret]]'s targeting laser.
*Wait for a few seconds for the Turret to travel to a bottomless area and then shoot the portal at the panels below the Funnel Receptacle.
*Go stand on the [[Heavy Duty Super-Colliding Super Button|button]] and wait for the [[Frankenturret]] to go through the portal.
*Shoot the same portal on the left of the wall you used to get rid of the Turret. Step off from the button.
*Frankenturret should come within your reach. Pick it up and place it on the button.
*Jump in the Funnel, wait until you are on the opposite side and then exit the Funnel.
*Shoot a portal on the wall next to you to get the Frankenturret off the button.
*Put a portal in front of the exit and go in the Funnel.
