The image above has left many people baffled. At first glance, it looks like a normal picture of three friends on a sunny day. However, there’s something strange that makes it stand out—something is missing.

Clues: It’s not about the women themselves or the background. The trick is not in what’s there, but in what’s missing. Can you spot it?

The mystery lies in the park bench. It appears that there’s no actual seat, making it look like the women are floating above the ground. “The women are suspended above the ground by an invisible bench.”

This image, originally shared on Imgur and picked up by the Daily Mail, has sparked debates online. Is it a clever Photoshop trick, or could the bench have pullout seats? As the Daily Mail suggests, it could be either, but many believe it’s “simply Photoshop.”

Regardless of how it was done, it certainly makes you think that invisible furniture could look “pretty freaking cool.”
