The world's smallest McDonald's just opened — but isn't for humans. Officially dubbed McHive, it's actually for bees. The project started in Sweden when the fast-food chain started putting beehives on their roofs to help support dwindling colonies. Now, the trend is starting to spread, with some restaurants even adding bee-friendly plants to their grass areas. Creative agency NORD DDB gets in on the action by building this miniature McDonald's replica, complete with a bee-sized fly-thru and teeny tiny arches.
