Holiday

A complex, homemade apparatus constructed from metal frames, glass containers, and tubing, decorated with string lights, is shown in operation; a small animal, likely a rodent, moves through the structure, climbing on the frame and navigating the tubes, while a digital display on the apparatus shows changing readings. The device is set up indoors on a countertop, with the animal's movement causing visible changes in the system, such as the flow of liquid or gas through the tubes.
