Build a small truck that is powered by 100% salt-water. The salt-water interacts with the included magnesium and copper sheets inside of the battery cartridge to create both a small positive and negative charge, which then powers the motor and spins the truck's wheels! This is a great educational kit that shows how salt-water can interact with other elements to create a sustainable electrical current. Detailed illustrated instructions are also included to help make assembly quick and easy.
Note: Requires table salt and a teaspoon for measuring.
