Saltwater-Powered Mini Car Physics Experiment DIY Kit - Creative Handmade Invention Science Experiment Set
Brand OOOToyz Weight 0.1kg Color As shown Materials multiple materials Suitable Age 7-14 years old The saltwater-powered mini car utilizes magnesium and carbon electrodes to generate electricity. When the magnesium electrode is immersed in the saltwater solution, it undergoes a chemical reaction known as oxidation. This reaction causes the magnesium to release electrons, which creates an electric current. On the other hand, the carbon electrode acts as the cathode in the system. It attracts the released electrons and allows them to flow through the circuit, powering the mini car. This process, known as electrochemical energy conversion, demonstrates the ability of saltwater to facilitate the transfer of electrons and generate electricity.
