Every once in a while, a perfectly timed photo sends the internet into a frenzy — and this optical illusion inside a drinking glass is no exception.
At first glance, it seems like a random splash of foam clinging to the side of a glass, likely after someone finished their beverage. But look again — there’s more to this than meets the eye. Depending on your perception style and how your brain processes visual information, you might see two very different things…
👁️ Right-Brained People — Creative, intuitive, and emotion-driven thinkers often say they see a fish swimming across the glass. They focus on the curves and fluidity of the image, interpreting it as an aquatic creature mid-swim.
🧠 Left-Brained People — Logical, analytical minds claim it looks like a mermaid — upright, with a torso, arms, and flowing tail. These viewers tend to seek structure and form, piecing together a humanoid figure from the bubbles and foam outlines.
This kind of image is a fun example of pareidolia, a phenomenon where people see familiar shapes or figures in random patterns or objects (like clouds or stains). And just like the famous “dress” that sparked debate over its color, this illusion splits people right down the middle.
Whether you see a fish, a mermaid, or something entirely different, it’s fascinating to realize how our brains process the same visual data in different ways. There’s no “correct” answer — only what your mind perceives first.
