Excursion Funnel

An Excursion Funnel

The Excursion Funnel, also known as the Tractor Beam, is a game 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 button.

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.

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.

Trivia

• When inside an Excursion Funnel in the single player campaign, soothing music plays, possibly to relate the tactile sensation of being weightless in a funnel. All other sound is blocked out or significantly dampened.

• In Super Mario Galaxy, there is something that looks similar to, and has a similar function to, the Excursion Funnel from Portal 2. It has the same blue swirls and transparency.

• In Portal, after GLaDOS' cores are detached, they are held up by what looks similar to an Excursion Funnel, however, it only holds the cores up and not the player.
• There is a glitch where, when having no velocity (Being completely still) and crouching will allow the player to fly. Firing a portal or not holding the crouch key will stop it, and going in an excursion funnel again will Reset the glitch.
