I don't think people can read, including, ironically, the OP; the title quite clearly says "useless superpower". I.e. A super power that is of no use. In other words, the power to turn a kettle into chocolate, but only when it is full of boiling water, and you have the intention of using the kettle to boil water for tea, or coffee. Should you change your mind and decide to use the melted chocolate for other means, it will disappear, along with the boiling water. [spoiler]Now waiting on the OP to edit his title, in an attempt to both save face, and make me look like an illiterate jackass. [/spoiler]
