Gasoline is costly and environmentally harmful, so who wouldn't want a car powered by salt water? When they build and play with this teachable toy, students learn about new forms of clean energy. They just add salt water and watch the Salt Water Fuel Car go! This environmentally and kid-friendly vehicle reflects the new, cleaner ways we think about automobile use and demonstrates a more effective use of our natural resources. Now teaching 'green' concepts is child's play! As salt water reacts with the magnesium metal sheet (three sheets included) in the fuel cell module, the car can operate for five to seven hours continuously. If you want to park the vehicle, simply take out the fuel cell module, rinse with tap water, and dry. All the materials used in this kit are environmentally clean, with no toxins or disposal concerns. It will not produce heat, so it is completely safe.
Refill includes five magnesium sheets, one air cathode, and one piece non-woven fabric.
