Step into the Crash Course dimension with our new augmented reality poster! Point your phone or tablet at it and watch the portal magically come to life. Who knows the mysteries it may hold? Watch as hosts from your favourite Crash Course shows appear in the space-time rift to bring you exclusive sneak peeks, fun facts, and easter eggs from another realm that you won't find anywhere else in the Crash Course universe, so the only question left to ask is: are you brave enough to enter?
