Science World After Dark turns sinister for our most spine-tingling event of the year. This ain't no kids Halloween party: adults 19+ are invited to explore a haunted dome with a bewitching brew, unsettling spectacles, and shock-worthy science. This is one of our top-selling After Dark events, so make sure you don't miss your chance to geek out at the gore and understand the science behind the horror. Miss it, and you'll wish you hadn't.
