Scientists have developed an incredible new type of robot that challenges our traditional understanding of what a robot can be. These tiny, innovative devices are made entirely from fish food and can move across water without any electronic components. Instead of using complex circuitry, these miniature "boats" rely on a fascinating chemical reaction that propels them forward.

The robots work through a clever scientific principle called the Marangoni effect, which essentially creates movement by manipulating surface tension in water. When the robot's internal chamber of citric acid and baking soda mixes with water, it generates carbon dioxide gas. This gas pushes a special liquid through a small opening, creating a unique propulsion mechanism that allows the robot to glide across water surfaces.

What makes these robots truly remarkable is their environmental friendliness. After completing their task – which could include delivering medication to fish farms or collecting scientific data about water environments – they completely dissolve and transform into fish food. This means they leave no trace behind and actually become a potential food source for aquatic life. The researchers hope this innovative approach could revolutionize underwater monitoring and research by creating completely biodegradable exploration tools.
