(Verse 1) In the heart of the Manhattan Project, a secret they did keep A sphere of plutonium, a power both to give and reap The Demon Core they called it, a name that chilled the bone For in its touch, a darkness lay, a horror all its own (Chorus) Oh, the Demon Core, a man-made horror, a nightmare born of science A force unleashed, a power untamed, a tragic, fatal defiance It whispered promises of progress, of a future bright and bold But in its wake, a chilling truth, a story yet untold (Verse 2) Harry Daghlian, a brilliant mind, a scientist so keen He sought to understand its power, the secrets it did glean But in a moment’s carelessness, a fatal dose he took The Demon Core’s embrace, a deadly, silent hook (Chorus) Oh, the Demon Core, a man-made horror, a nightmare born of science A force unleashed, a power untamed, a tragic, fatal defiance It whispered promises of progress, of a future bright and bold But in its wake, a chilling truth, a story yet untold (Verse 3) Then came the turn of Louis Slotin, a man of wisdom deep He knew the dangers lurking, the secrets it would keep But in a fateful experiment, a screwdriver slipped its hold The Demon Core’s embrace, a story yet untold (Chorus) Oh, the Demon Core, a man-made horror, a nightmare born of science A force unleashed, a power untamed, a tragic, fatal defiance It whispered promises of progress, of a future bright and bold But in its wake, a chilling truth, a story yet untold (Bridge) The Demon Core, a symbol of the power we wield A reminder of the dangers, the secrets we conceal A cautionary tale, a lesson learned in pain That knowledge unchecked, can lead to madness and insane (Chorus) Oh, the Demon Core, a man-made horror, a nightmare born of science A force unleashed, a power untamed, a tragic, fatal defiance It whispered promises of progress, of a future bright and bold But in its wake, a chilling truth, a story yet untold (Outro) The Demon Core, a chilling legacy, a reminder of our might A testament to the darkness, that lurks within the light A man-made horror, a story etched in time A warning to humanity, to tread with care and climb.
