Aperture Science Material Emancipation Grill

"Please be advised that a noticeable taste of blood is not part of any test protocol but is an unintended side effect of the Aperture Science Material Emancipation Grid, which may, in semi-rare cases, emancipate dental fillings, crowns, tooth enamel, and teeth."

- GLaDOS

The Aperture Science Material Emancipation Grid is an energy field featured at the end of each Aperture Science Enrichment Center Test Chamber, right before any elevator, and within some Test Chambers where they are part of the test.

Overview



 * Its purpose is mostly to "reboot" any portal created with the ASHPD. In that way each Test Subject starts each new Test Chamber with a "clean" portal network, and must use their assets properly when having to come across one several times during tests.


 * The Material Emancipation Grid's design is a similar, albeit sleeker form of the Combine's Force Field, but in a semi-reverse fashion: It allows anyone through, but not inanimate objects. The sides are two curved emitters with a pair of blue stripes on each, which disperse waves of glowing particles, slowly moving from one side to the other.


 * According to GLaDOS, the Material Emancipation Grid vaporizes any unauthorized equipment that passes through it, such as Weighted Storage Cubes or any other prop. It also apparently "emancipates" dental fillings, crowns, tooth enamel, and teeth. She also states that a noticeable taste of blood may occur, although it is an unintended side effect.


 * Whenever an object (besides the ASHPD) goes through the Material Emancipation Grid, it turns black, then disintegrates, just like objects hit with the alternate fire of an AR2.


 * Each time Chell passes through a Material Emancipation Grid, the ASHPD will slightly shake and the light on its body will turn off until fired again, showing the portal "reboot".


 * When being put through a Material Emancipation Grid, a Sentry Gun will emit a long "ayayayayay" and vaporize, whether it is disabled or not.


 * A small Material Emancipation Grid can be found in the office areas.


 * When a radio is brought through the Material Emancipation Grid, its music stops as the radio disintegrates.


 * As seen on one of its blueprints, the Borealis contains a Material Emancipation Grid.

Trivia
The Material Emancipation Grid is sometimes referred to as "Grill" both in audio files and subtitles. "Grid" is used here as it is the term used in scripts.
