Why it worked
The video likely worked due to its uncanny and slightly unsettling visual of a realistic eyeball prop, combined with the 'experiment' framing which sparks curiosity. The short, engaging format and the unusual subject matter would have captured attention.
Summary
The video shows a person interacting with a large, realistic-looking eyeball prop. The eyeball appears to be made of a material that can be manipulated and placed into a plastic bag. The experiment seems to be focused on the visual and tactile properties of the prop.
