This is from our family's annual Christmas play. The foil helmets that the boys are wearing are good conductors of electricity. That means that if a potential lightning bolt were to suddenly strike, my brother would be the one who would get hit (haha) because he's the tallest. If an electric charge were to be applied to the foil on the tip of the spear, my cousin would probably not get severely shocked since the spear has a wooden handle and wood is an insulator.
