McDonald's has opened the "world's smallest restaurant" in Sweden - it's so small, you can't actually go in.
Instead, the tiny replica of a McDonald's restaurant is to cater to the needs of a very different kind of customer - bees.
The 'McHive' - which is complete with fully functioning seating, a drive-thru area, and the famous golden arches logo - is designed to be placed on top of McDonald's outlets around the world, starting in Sweden, where five have already been installed.
The campaign is designed to draw attention to the world's struggling bee population. Bees are of course a crucial component in the life cycle of flowers and plants - and thus much of the world's food supply. But due to insecticides, industrial agriculture, and climate changes, their numbers are in decline.
Christoffer Rönnblad, marketing director of McDonald's Sweden, said in a statement: "We have a lot of really devoted franchisees who contribute to our sustainability work, and it feels good that we can use our size to amplify such a great idea as beehives on the rooftops."
