Green Science: Salt-Powered Robot

Build a miniature robot racer and bring it to life using the surprising power of salt water. After assembling the chassis, wheels, motor, and specially designed power cartridge, simply add salt water and watch the robot race across the floor. The hands-on project seamlessly introduces alternative energy, chemical reactions, electricity, robotics, and mechanical engineering while strengthening problem-solving, logical thinking, and construction skills. The kit includes two sets of power sheets that can be reused when properly cleaned and dried. No batteries are required.
