a Chicken Powered Nuclear Bomb ?! ;)
so many elements are recorded in history, for various reasons.. but some of them get into history for weird reasons..
well, the story s abt a nuclear bomb named Blue Peacock, but otherwise known as the Chicken Powered Nuclear Bomb..
apparently, the bomb was a nuclear landmine designed by UK, supposed to be planted at prime locations of Germany during WWII.. but it got it's name because of an interesting proposal made during the design of the bomb.. the designers proposed to have a casing which could house chickens :O and the chicken housing was proposed to keep the internal electronics warm and functioning (using the body heat generated by the chickens!)..

wow! I feel compelled to appreciate the genius behind the idea [LOL]
add to that, this news was revealed to the public on an April 1^st!
