Photo: Girl using hair dryer Electricity is a mystery. No one has ever observed it or heard it or felt it. We can see and hear and feel only what electricity does. We know that it makes light bulbs shine and irons heat up and telephones ring. But we cannot say what electricity itself is like. We cannot even say where clectricity comes from. Some scientists think that the sun may be the source of most electricity. Others think that the movement of the earth produces some of it. All anyone knows is that electricity seems to be everywhere and that there are many ways to bring it forth. How would you have to change the way you.get ready for school if you did not use electricity? “The voice of thy thunder was in the heaven: the lightnings lightened the world: the earth trembled and shook.” Psalm 77:18 40
