This gives me a major combat advantage, hopefully.<br /> }}<br /> <br /> ==Explanation==<br /> A {{w|Faraday cage}} is a cage of conducting material that interferes and blocks out {{w|electromagnetic radiation}} like cell phone signals, provided the material is of the appropriate thickness and the gaps between the &quot;bars&quot; are significantly smaller than the wavelength of the radiation. A {{w|cage match}} is a type of wrestling match in which the participants fight in a ring enclosed by a metal cage. The comic caption is a play on the two terms, putting [[Cueball]] into a cage match in the Faraday cage that is blocking his reception.<br /> <br /> The title text is a play on a rule in cage matches that states that a participant wins if they are first to escape the cage. {{w|Tunneling_diode|Tunneling diodes}} are capable of fast operation, allowing a device to generate high frequency signals, which are more capable of penetrating the mesh openings in a Faraday cage.<br /> <br /> ==Transcript==<br /> :[Cueball looking at a phone in his hands]<br /> :Cueball: Man, the coverage here is ''Awfu-''<br /> <br /> :[Man punches Cueball]<br /> <br /> :Faraday cagematch<br /> {{comic discussion}} <br /> [[Category:Comics featuring Cueball]]<br /> [[Category:Physics]]</div>
