The '''Excursion Funnel''' is a testing element used in the Aperture Science Enrichment Center|Enrichment Center several decades after ''Portal'', and appears in ''Portal 2''.
==Overview==
FileFunnel inside.jpg|thumb|left|200px|Inside an Excursion Funnel, facing its emitter.
*Created from at least 1998, Excursion Funnels are used by Aperture Science as part of an investigation into how well Test Subjects can solve problems while traveling violently through a churning funnel of liquid WikipediaAsbestos|asbestos. According to the Aperture Science scientists, results as far as 1998 were highly informative; they cannot.
*Acting as a WikipediaTractor beam|tractor beam, the Excursion Funnel is powered by a round emitter placed on a wall, containing three gleaming, blue orbs. From each orb leaves a thread that swirls on itself in a spiral, the three threads making up the Funnel itself, a seemingly infinite transparent blue cylinder.http//www.youtube.com/watch?v=cFWkng6biNI Excursion Funnel demonstration on Combine OverWiki's YouTube channel Combined with Teleportation|portals, it can transport Test Subjects or objects to otherwise unreachable areas.
*The Excursion Funnel can be reversed in certain test chambers by activating a 1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button. This causes the funnel to turn orange and attract objects instead of repelling them.
*"''Asbestos is harmless!''" appears to be the Excursion Funnel's slogan, and a registered trademark of Aperture Science.
*If the player is about to die through misplacing a portal that is redirecting an Excursion Funnel, the game automatically rearranges their portals to save them from death.Dave Saunders states in the Developer commentary ''Excursion Funnel'' "''As a solution, we now detect when the player places the wrong portal in hopes of saving themselves; we help them out by moving their other portal under the excursion funnel source.''"
*The mechanics of the "liquid asbestos" aspect of excursion funnels is currently unknown. It is likely that the device generates a type of tractor beam, which propels a liquid mixture of several elements, one of these being liquified asbestos.

==Behind the scenes==
FileExcursion funnel poster first.jpg|The original diagram, with a Super Button in place of the emitter.|thumb|200px
The Excursion Funnel was first revealed through a diagram in the April, 2010 issue of Game Informer. In the diagram, a 1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button serves as a placeholder for the Funnel's emitter. For an updated (and moving) diagram revealed during E3 2010, the Button was replaced by the definitive device.
==Trivia==
So far it is unknown why while the Excursion Funnel was already in use in 1998 as it is not seen in the first ''Portal'', set over 20 years later.http//gameinformer.com/b/podcasts/archive/2010/03/26/special-edition-podcast-portal-2.aspx Special Edition Podcast Portal 2 - podcast on Game Informer However, it is likely that Chell simply did not venture into Test Chambers containing the Excursion Funnel during this time.
