Hawkins National Laboratory is the fictional government research facility at the centre of Stranger Things, the Netflix series that premiered in 2016, where secret experiments open a doorway to the Upside Down. Its alarm is heard during containment failures and emergency lockdowns inside the lab, moments that helped make the location feel dangerous and out of control. As clips from the show spread through edits, reaction videos and soundboards, the alarm became shorthand for a scientific disaster or a hidden threat, and creators still use it to turn an ordinary scene into an emergency.
