An Excursion Funnel is a new type of technology introduced in Portal 2. This mechanism creates a funnel of energy in which the player may enter and exit at any time. It seems to defy the laws of gravity, allowing any who enter to become weightless and travel along the path of the funnel. Anyone, or anything, caught inside the funnel cannot go backwards willingly, and must rely on the Excursion Funnel reversing, generally through use of a button.
Excursion Funnels can act through portals and therefore can be used to solve puzzles where the funnels may seem not useful on first glance to the solving of a test. If a Excursion Funnel is reversed then it is possible for objects to go through portals in which the funnel is acting through.
The funnel can also act as a mode of transportation for objects across large gaps, as well as gels. Gels caught in the Excursion Funnel are slowly forced along a path until it collides with a wall or the funnel suddenly disappears, making it excellent for covering large areas in a short amount of time. Turrets coated in Repulsion Gel are instantly thrown into the air, bouncing helplessly until they shutdown.
