Breaking Yura

A young man in a black jacket and blue hoodie stands at a counter in a classroom or lab, repeatedly dipping a thin stick into a small container while holding a clear tube, as another young man watches from behind. The man in the foreground turns to his right, reaches for a bottle on a shelf, then returns to the counter to continue the action, with a periodic motion of dipping the stick into the container. The setting is a room with light blue walls, a long counter, shelves with various bottles and glassware, and a periodic table on the wall.
