C-4 charges, as seen in The Thing (2002).

C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C. The British version of the explosive is known as PE-4 (Plastic Explosive). C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.

C-4 has a texture similar to modeling clay and can be molded into any desired shape. C-4 is stable and an explosion can only be initiated by a shock wave from a detonator.

The Thing (2002)

C-4 charges were used in The Thing (2002) to wipe out the remains of the devastated U.S. Outpost 31 and to stop the fleet of planes Whitley planned on using to spread the infection globally. They are usable only by placing them on the designated targets and cannot be placed anywhere freely. C-4 charges were also used by Whitley's Black Ops as traps, activated by laser motion sensors.
