<P> In the 74th Hunger Games, Rue uses an unnamed plant's leaves to treat Katniss' tracker jacker stings . Katniss recognizes the leaves as something that her mother used, but by a different method . While Rue utilizes the leaves by chewing them into a pulp then applying them directly to the tracker jacker stings, Katniss' mother stewed the leaves to make an infusion which the patient then drinks . Also in the 74th Hunger Games, Katniss applies the leaves of the same plant to Peeta's leg wound (inflicted by Cato) in the hope of warding off infection . The application causes pus to run out of his leg and the swelling to go down temporarily . </P> <P> The Capitol controls all TV broadcasts within Panem . Sometimes there are emergency announcements that make the TV start itself, like the Hunger Games, news bulletins or warnings . </P> <P> High speed trains run throughout the districts . The trains are known for their speed and comfort . They are the trains that carry the tributes . </P> <P> Electromagnetic force fields are used by the Capitol as barriers, mainly in the arenas, where the fields are camouflaged to match the arena's terrain . In the Second Quarter Quell, Haymitch used the force field as a weapon against a District 1 tribute . In the Third Quarter Quell, Peeta accidentally hits the force field while walking through the tropical arena . Blight, the male district 7 tribute is killed when stumbling upon the force field during the blood rain in that sector . Katniss also shoots an arrow at the force field to destroy it in the same Quarter Quell . </P>
