Speakers. Fascinating objects, aren't they? Amplifying the volume of your, let's say phone, to a possibly stupendous level. They are the birth and death of a good party/club, and can be made at minuscule sizes. It is truly a wondrous invention. Adjustable volume, so it can be ear-shatteringly loud or as quiet as the audience of the queen's Christmas speech. [spoiler]Good enough for ya Qwerty?[/spoiler]
