Harness the power of electrochemistry! This combo pack includes two separate DIY builds: a salt water powered fan and a bright LED light. Generate electricity using nothing but salt water and metal electrodes. Watch the fan spin and the light glow, driven entirely by a safe, visible chemical reaction. No disposable batteries required—just add salt and water. Perfect for tech enthusiasts, desk setups, or as a fascinating conversation piece.
