Hi Product Hunt! 👋 I’m a software industry professional and dad of a 3.5-year-old. One rainy afternoon, my son pressed his face against the window and asked: “Dad, where does rain come from?” I explained evaporation, clouds, precipitation — he stared blankly and went back to watching the rain. That’s when I realized: words don’t work for young kids. They need to see it. So I spent two weeks building Wonder Why? — a collection of HTML web animations that visually explain the science behind everyday phenomena, in language a 3-year-old can actually follow. What’s inside: 🌧️ Why does it rain? — Follow a water droplet as it evaporates, floats up, forms a cloud, and falls back down 🌙 Why do day and night take turns? — Watch the Earth spin in space, with a tiny marker showing “we live here” 🌈 Why do rainbows appear? — A beam of sunlight enters a raindrop and splits into 7 colors 💧 The Magic of Freezing Water — Drag a thermometer and watch water turn to ice 🌱 Growing a Seed — Give a seed water and sunlight, watch it sprout step by step 🕯️ Why does a candle go out? — Cover it with a glass and watch oxygen run out Key design decisions: No app, no download — just open a link. Parents can share via WeChat, iMessage, anywhere No voiceover on purpose — the subtitles are there for parents to read aloud. Your voice is the best voice for your child Scientifically accurate — I caught myself almost using “Earth’s distance from the Sun” to explain seasons (a common myth!). Every animation went through fact-checking before publishing 4 languages — Chinese, English, Japanese, Vietnamese I’d love to hear your feedback — especially from parents. What questions does your kid ask that you never know how to answer? 🔗 wonderwhy.cc
