A hand is holding a clear glass beaker with a dark purple liquid inside. The beaker is tilted slightly, and the liquid is visible at the top. The hand is blurred in the image. The background is out of focus and is a white room with a wooden table and chairs. The image was taken in Zografou, Greece, at the coordinates 37.968, 23.785. It is unclear what the liquid is or the context in which it was photographed.
