My 7/26 poster: "Why is the sky blue?" for the endless-why kids 🔭

# For every kid who asks "why?" a hundred times My **7/26 poster**: "Why is the sky blue?" — drawn for younger kids who never stop asking. 为爱问为什么的孩子而画。 ## On the poster - Sunlight is secretly every color - Air scatters the blue ones all over the sky - A little experiment they can do with a glass of water A 7-year-old stood at my poster and asked *four* follow-up questions. That is a win — curiosity is contagious, and the poster wall is where it spreads. 好奇,会传染。 🔭
