The Aperture Science Handheld Portal Device (HPD) is an experimental tool used to create two connected interdimensional portals through which objects can pass. The HPD fires two types or "colors" of portals. The first type of portal will be outlined in a blue haze, the second orange. Objects exiting through one will reenter through the other. As a result, the HPD is useful when trying to overcome obstacles which would otherwise be impassable.

The HPD has two triggers that each shoots a small ball of plasma energy. When a ball makes contact with an appropriate surface, it will flash open into a portal of one of the two colors. If a pre-existing colored portal exists, a new one of the same color fired will replace the old one. If no other portals are open, a portal's "halo" will appear, but there will be no "opening" leading to the other non-existent portal.

Portals are 6' in diameter and will only appear on flat surfaces (concrete, metal, plastic). Portals cannot be placed on natural materials (dirt, water) nor any irregularly shaped surfaces (curves or cracked surfaces). A portal cannot be placed on a surface smaller than the portal's required 6' diameter. If an attempt is made to place an illegal portal, the plasma ball will just strike the surface and dissipate. A plasma ball cannot be used as a weapon either since the ball will harmlessly disappear if it strikes living tissue.

Travel through an HPD's portals is instantaneous - like walking through a doorway. One interesting feature is the Law of Conservation of Motion. If you pass through one at a high rate of speed, you will be traveling at that same rate of speed when you exit the other portal. Portals cannot be "turned off" at will but they can be "replaced" with another portal elsewhere. They will also fade away (click off) after 30 minutes. A portal gun can fire 10 plasma balls before being drained.

Though the portals have been proven 100% safe, the Handheld Portal Device itself has not. According to GLaDOS.

"Do not touch the operational end of the device. Do not look into the operational end of the device. Do not submerge the device in liquid, even partially. Most important, under no circumstances should you- (static)."

NOTE: This device is based on the portal gun from, well, you know. Hope you like it. I certainly do. In fact, it's hard to overstate my satisfaction. (Heh.)
