This is bound to bring some joy to your day. Everything about it is delightful.
(And the engineering is amazing.)
Two women wearing hijabs in a backyard with bright green grass. It is well-lit in the blackness of night. One is riding an exercise bike that is moving a chain connected to a mini pink roller coaster, where the second woman is sitting in a coaster cart. They are laughing while the rider is hoisted up to the top of the hill, before dropping into the small round of the full coaster. Behind them, many children are playing on some swinging toys in a unique, seemingly-homemade, and well-lit playground structure of some sort.
