Watch this clever robot spring to life powered by nothing but salt water! Thames & Kosmos has engineered a fascinating metal-air fuel cell that transforms a simple saltwater solution into electrical energy. As the innovative pump mechanism delivers tiny droplets onto magnesium plates, your robot marches forward for up to an hour on just one drop. Perfect for young scientists curious about electrochemistry, electric currents, and energy storage. The reusable fuel bottle is a breeze to clean and refill, unlocking endless hours of salty, scientific fun.
