Girl Stuck In Concrete Illusion
Also known as: Concrete Girl · Girl Sinking Into Sidewalk
Girl Stuck In Concrete Illusion is a viral optical illusion photo posted to Reddit in May 2021 showing a young girl who appears to be sinking into a paved street. The image, posted by the girl's mother, sparked thousands of confused comments before viewers figured out the child was simply standing behind a low concrete wall that blends seamlessly with the sidewalk in front of her.
Overview
The photo shows a young girl dressed in pink standing outdoors on a concrete path, holding up what appears to be a cellphone. Her lower body is completely invisible, creating the startling impression that she's buried waist-deep in the pavement like it's quicksand4. The illusion works because the girl is standing behind a short retaining wall made of the same material as the sidewalk in front of her. The wall's top edge lines up perfectly with the path, making both surfaces look like a single flat plane2. Her elbow resting on the wall at exactly the right height and her shadow falling on top of it further sell the trick1.
On May 6, 2021, Reddit user u/MK24ever posted the image to the r/confusing_perspective subreddit with the title "My daughter, where's the rest of her?! Ohh I see, do you?"4. The caption teased that an explanation existed while challenging viewers to find it themselves. Later that same day, u/MK24ever followed up with a labeled version of the image in the comments to help people see where the wall was4.
The post blew up fast. It pulled in over 69,200 upvotes and 1,200 comments within two weeks1. Many commenters admitted they couldn't figure it out even after reading explanations from others.

Cultural Impact
Fun Facts
The original Reddit post hit r/confusing_perspective, a subreddit dedicated to photos where depth and perspective create misleading visuals.
The girl's elbow placement was a key reason the illusion worked so well. It rested at the exact same height as the top of the wall, making the wall disappear into the sidewalk.
Multiple people independently created annotated "solution" images with drawn lines showing where the wall is, but many viewers said even the annotations didn't immediately help.
One commenter sarcastically bragged: "I don't have to come to the comments. I knew right away she was only half a person".
