In a bid to prolong bed-time, my four-year-old just asked me, "What is electricity made of?' I told her to close her eyes and go to sleep, which has bought me 9-10 hours till she wakes me up and asks me the same question again. What's the most accurate answer I can give her that she will understand and not be bored by?
