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 [[Heavy Duty Super-Colliding Super Button|button]].
The '''Excursion Funnel''', also known as the '''Tractor Beam''', is a game [[Mechanics|mechanic]] introduced in ''Portal 2''. The mechanism creates a wide cylindrical beam of blue light that the player may enter or exit at any time. It seems to defy the laws of gravity, allowing anything/anyone who enters to become weightless and travel along the path of the Funnel. Anyone or anything caught inside the Funnel travels in the direction that the Funnel is flowing in, unless the Funnel is reversed, which is usually accomplished through the activation of a [[Heavy Duty Super-Colliding Super Button|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.
Excursion Funnels can pass through portals and can cross vast distances, and can, therefore, be used to solve puzzles in which Funnels may not initially appear to be useful.
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.
Excursion Funnels can also act as a mode of transportation for the player or objects across large gaps, as well as [[Gels]]. Gels caught in the Excursion Funnel will slowly follow the direction of the Funnel until the substance collides with a wall or until the Funnel is deactivated, making funnels useful for coating large areas in a short amount of time.
