&lt;div&gt;[[File:Portal PortalGun.png|right|thumb|The Handheld Portal Device model from &#039;&#039;[[Portal]]&#039;&#039;.|250px]]&lt;br /&gt;
The &#039;&#039;&#039;[[Aperture Science]] Handheld Portal Device&#039;&#039;&#039; (also known as the &#039;&#039;&#039;Portal Gun&#039;&#039;&#039; or &#039;&#039;&#039;ASHPD&#039;&#039;&#039;) is the experimental tool designed to place two [[portals]] that objects can pass through. This is the primary tool players are equipped with to complete [[Test Chamber]]s.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
The Handheld Portal Device is designed to create and place portals on any white [[surface]] that is immobile, flat and large enough. When the device is fired, a colored projectile will be emitted from the barrel. If the projectile strikes a valid surface, a portal of the corresponding colour will be formed. If a portal of the other colour is already placed, these two portals will be linked. If a portal of the same colour is already placed, it will be closed and the new one will be used instead, limiting the player to the use of only two portals at a time. The glass chamber and a light on the top of the device will glow with the colour of the previously placed portal. &lt;br /&gt;
&lt;br /&gt;
The Handheld Portal Device also has the ability to pick up and manipulate objects directly in front of it in the same manner as the [[hl2:Gravity Gun|Gravity Gun]] from the &#039;&#039;Half-Life&#039;&#039; series. It cannot launch objects like the Gravity Gun, but can carry heavy objects, even through portals.&lt;br /&gt;

{{Quotation|&#039;&#039;&#039;Cave Johnson&#039;&#039;&#039;|I&#039;m Cave Johnson. I own the place.|sound=Cave_Johnson_fifties_intro04.wav}}&lt;br /&gt;
&#039;&#039;&#039;Cave Johnson&#039;&#039;&#039; is the founder of [[Aperture Science]], which was built from Aperture Science Innovations. He was briefly mentioned in &#039;&#039;[[Portal]]&#039;&#039;, but becomes a more prominent character in &#039;&#039;[[Portal 2]]&#039;&#039;, in the form of tape recordings he leaves behind. {{spoiler text|His current status and whereabouts are unknown, presumed dead.}}&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
=== Shower curtains ===&lt;br /&gt;
In 1953 Cave Johnson sets up Aperture Fixtures, a shower curtain manufacturer. The precursor to Aperture Science, he chooses the name because it &#039;makes the curtains sound more hygienic&#039;. He becomes a billionaire after winning contracts to manufacture the US Military&#039;s shower curtains.&lt;br /&gt;
&lt;br /&gt;
==== Aperture Science Innovations====&lt;br /&gt;
During his career in science, he called on the wealthy or power elite to join his cause for the future of science, as well as those with the brains, much like Caroline, and those lacking common sense for the dangers of science. {{spoiler text|Most of his ideas were wild and, more often than not, lethal. Some experiments involved replacing the test subjects blood with gasoline, while another exposed a tester to jet engines to lower the amount of water in the human body, stating it seemed &#039;excessive&#039;. Most of his crackpot ideas turn out to be massive failures, leaving only a few that seem to be remotely useful. Ideas such as the [[Gels|gels]] that appear during the later stages of the game, namely Propulsion Gel and Repulsion Gel. }}&lt;br /&gt;
&lt;br /&gt;
==== Aperture ====&lt;br /&gt;
At the time of creation, Aperture Science Innovations had created {{spoiler text|the Aperture Science Portable Quantum Tunneling Device,}} a prototype to the modern [[Handheld Portal Device]] Chell wields. {{spoiler text|It seems Aperture had already begun to perfect the portal technology, but was not ready to unleash it to the world, thinking much more could be done than just portals. Of course, the technology was impractical and bulky, coupled with Cave&#039;s wild innovations. During the 70s, Aperture Science had become known as just &#039;Aperture&#039;, with the rise and competition of Black Mesa already putting Cave&#039;s temper to its limits. It was also around this time that Caroline became a bigger part of Cave&#039;s life as a secretary. It&#039;s also around this time where Cave becomes more desperate in his struggle to continue the life of his career and company through incentives, even if they were low-ball offers to lure potential test subjects to their doom.}}&lt;br /&gt;

{{See also|Aperture Science}}&lt;br /&gt;
Sometime during the 80&#039;s, Cave Johnson had renamed the company Aperture Science, a name that would be known far into the future. However, the number of willing test subjects has dwindled over the years, and it grows to the point where employees and random strangers are pulled off the streets to be a part of the testing. The technology has advanced greatly, where robots are beginning to replace human employees. Said employees then become unfortunate victims of science in Cave&#039;s visions of the future of science.&lt;br /&gt;
&lt;br /&gt;
{{spoiler text|During his final days, he states he has tried to purchase a number of &amp;quot;moon rocks&amp;quot;. However, his last few recordings indicate that these acquired &amp;quot;moon rocks&amp;quot; have caused him great illness. He explains that, in one of his wild ideas, he was grounding moon rocks together in the name of science to form a new type of substance called the &#039;Conversion Gel&#039;, most likely named due to it&#039;s ability to serve as a great portal conductor by converting covered materials into suitable surfaces to place [[Portals]] on. However, With his terminal illness still growing worse and with no cure available, he decides to re-purpose the &#039;conversion gel&#039; to create new portals that would hopefully sap the poison out of him. &lt;br /&gt;
&lt;br /&gt;
With little hope of a cure left, he instructs his engineers to start research on {{W|artificial intelligence}} (AI) and {{W|brain mapping}} in the hopes his brain can be downloaded onto a computer, stating they &amp;quot;should&#039;ve been doing this 30 years ago&amp;quot;. He also states that if he were to die before the technology is released, he leaves instructions that his secretary [[Caroline]] will take charge of Aperture Science. He states that he knows she&#039;ll decline at first or feel she can&#039;t do it, which he follows up with &amp;quot;Force her to do it if you have to&amp;quot;. It is unknown what becomes of him, but it is presumed he fell victim to the illness, and ultimately, to science.}}&lt;br /&gt;

{{Quotation|&#039;&#039;&#039;Cave Johnson&#039;&#039;&#039;|We haven&#039;t entirely nailed down what element it is yet, but I&#039;ll tell you this: it&#039;s a lively one, and it does NOT like the human skeleton.|sound=Cave_Johnson_fifties_second_test_complete02.wav}}&lt;br /&gt;
&#039;&#039;&#039;Gels&#039;&#039;&#039; are a gameplay implement introduced in &#039;&#039;[[Portal 2]]&#039;&#039;. They are paint-like liquids that impart different effects on [[surfaces]] and objects.&lt;br /&gt;
&lt;br /&gt;
== Gels ==&lt;br /&gt;
=== Repulsion Gel ===&lt;br /&gt;
Repulsion Gel is a light blue substance that repels objects. A player or an object that hits a surface coated with it bounces off. Jumping off such a surface launches the player higher than a normal jump. Objects such as [[Storage Cube]]s and [[Turrets]] can be covered in Repulsion Gel, which causes them to bounce around erratically.&lt;br /&gt;
&lt;br /&gt;
=== Propulsion Gel ===&lt;br /&gt;
A bright orange gel that greatly increases object velocity and reduces friction of objects moving on surfaces it is applied to. Objects covered in Propulsion Gel similarly have their friction reduced, causing them to slide around.&lt;br /&gt;
&lt;br /&gt;
=== Conversion Gel ===&lt;br /&gt;
Conversion Gel is a portal-conducting white liquid {{spoiler text|made from ground moon rocks}}. It enables the player to place portals on [[surfaces]] that originally are not &#039;&#039;portal conductive&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
=== Water ===&lt;br /&gt;
Water washes off other gels from surfaces and objects. It has no special properties towards gameplay and does not stick to surfaces.&lt;br /&gt;

&lt;div&gt;[[File:Portal PortalGun.png|right|thumb|The Handheld Portal Device model from &#039;&#039;[[Portal]]&#039;&#039;.|250px]]&lt;br /&gt;
The &#039;&#039;&#039;[[Aperture Science]] Handheld Portal Device&#039;&#039;&#039; (also known as the &#039;&#039;&#039;Portal Gun&#039;&#039;&#039; or &#039;&#039;&#039;ASHPD&#039;&#039;&#039;) is the experimental tool designed to place two [[portals]] that objects can pass through. This is the primary tool players are equipped with to complete [[Test Chamber]]s.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
The Handheld Portal Device is designed to create and place portals on any white [[surface]] that is immobile, flat and large enough. When the device is fired, a colored projectile will be emitted from the barrel. If the projectile strikes a valid surface, a portal of the corresponding colour will be formed. If a portal of the other colour is already placed, these two portals will be linked. If a portal of the same colour is already placed, it will be closed and the new one will be used instead, limiting the player to the use of only two portals at a time. The glass chamber and a light on the top of the device will glow with the colour of the previously placed portal. &lt;br /&gt;
&lt;br /&gt;
The Handheld Portal Device also has the ability to pick up and manipulate objects directly in front of it in the same manner as the [[hl2:Gravity Gun|Gravity Gun]] from the &#039;&#039;Half-Life&#039;&#039; series. It cannot launch objects like the Gravity Gun, but can carry heavy objects, even through portals.&lt;br /&gt;
