-A '''tin foil hat''' is a new [[Randomized appearance|appearance]] for unidentified [[helm]]s in [[SporkHack]], as well as a new non-randomized helm in [[UnNetHack]].
+A tinfoil hat has no [[weight]], and takes only one action to wear or [[remove]].
-The tin foil hat protects the wearer from damage from a (master) [[mind flayer]]'s psychic blast, with the downside that it also prevents the wearer from sensing monsters by [[telepathy]].  This applies to any active source of telepathy the player has&mdash;including, in SporkHack, the helm itself, if it happens to be the random appearance of the [[helm of telepathy]].  This means that in any game in SporkHack, there is a possibility that you will not be able to count on a helm of telepathy being an effective source of ESP for your [[ascension kit]].
+==Strategy==
-In UnNetHack, the tin foil hat is [[weight]]less and made of [[metal]] (which does not [[Erosion|rust or corrode]]), and, like the [[dented pot]], does not require a full [[turn]] to [[wear]] if the player is [[fast]].  However, it does not contribute to the wearer's [[AC]], giving it little value apart from its psychic protection.  With a base price of only one [[zorkmid]], surplus tin foil hats are probably not even worth saving for the next [[shop]] you encounter.
+==History==
-{{clear}}
+The tinfoil hat is added in version 3.5.1 via [https://github.com/UnNetHack/UnNetHack/commit/2c4d08abbcfe730a0aaf9cb17d9916b7df66024e commit 2c4d08ab].
 ==Origin==
 {{wikipedia|Tin foil hat}}
-Tin foil hats are head coverings made from aluminum ("tin") foil, which (supposedly) protect against attempts (by government organizations, spies, extraterrestrials, etc.) to read or control the wearer's mind.  The theory is that the foil functions as a [[Wikipedia:Faraday cage|Faraday cage]], a device that prevents electromagnetic waves from entering a space, in this case the wearer's brain.  In practice, however, foil wrapped around the head does not make an effective Faraday cage.  (Real Faraday cages are made by sufficiently enclosing spaces with metal sheets or grids.)
+Because of the questionable-at-best theories behind them, tin foil hats are stereotypically associated with conspiracy theories and paranoia, which gives the phrase "tin foil hat" a generally negative connotation. Some communities have "redeemed" the concept, though, with tongue-in-cheek tin foil hat design contests.
