Earlier today, New Yorkers were treated to a sweet, secret treat: the "Oreo Wonder Vault."

A bright blue door, found on 18th Street between 7th and 8th Avenues, featured a large Oreo on hinges and a cryptic message that said "open here." Curious (and hungry) people who opened the cookie-shaped door found a red lever. Pulling it summoned a pack of Filled Cupcake Oreos a whole six days before their official arrival in stores.

"Media and fans that stop by today will get the chance to personally open an Oreo shaped door and watch their box of Filled Cupcake Flavored Oreo Cookies 'travel' directly to their hands, traversing through a magical world of Oreo flavor," Mondelez International, the company that makes Oreo, said.

Buzzfeed's Arielle Calderon made the trip over and took a video of the whimsical delivery:
