What happens when fortune telling fish is underwater?

When fortune telling fish are placed underwater, they absorb the water and begin to move or curl in response to the moisture. This movement is often interpreted as a form of fortune telling, where the direction and manner of the fish's movements are said to reveal insights about a person's romantic prospects or personality traits. The fish typically reacts by curling up, straightening, or bending in specific ways, depending on the type of fortune it is meant to convey. However, it's important to remember that this is simply a novelty item and not based on any scientific principles.
