Above this is a globe as a planet actually looks: from far away a plain blue ball, almost all of it water. Detail only arrives as you come closer — first the borders, then the names of countries with the biggest first, then the capitals and the great rivers, and last of all the mountains, the wonders of the world and a hundred animals standing on the surface as tiny figures.
Everything you can see there is clickable, and everything you click has a page of its own. There are 810 of them across two languages: countries, continents, mountains, rivers, wonders of the world, animals, record lists, why-questions, a glossary and four quizzes.
Every country page gives the capital, area, population, neighbours, languages and currency, draws the country's real outline with its capital marked, and puts it in proportion: how big it is against the world, where it stands among its neighbours, which animals live there in the wild. The mountains, rivers and wonders are written by hand and checked one at a time, with the story behind each and the questions children actually ask.
The why-pages answer the questions grown-ups tend to shrug at — why the sea is blue, why there are time zones, why we have seasons — each with the real mechanism and something to try at home. The quizzes have no clock and no streak to lose: miss a question and you get a link at the end to the page that explains it.
Written for children of roughly eight to twelve, and built so that curiosity is the only thing needed. There is no account and no sign-up, and nobody is counted unless they explicitly agree in the banner. What you have visited on the globe is kept in your own browser's storage and never leaves your device. There are no notifications, nothing that expires overnight, and nothing that is lost by staying away for a week.
The figures come from public datasets and are named rather than asserted: borders from Natural Earth, country data from the ISO 3166 dataset, population from the World Bank. Where sources genuinely disagree — whether the Nile or the Amazon is longer, how tall Mont Blanc is with its ice cap changing every year — the page says so instead of picking an answer and pretending there was never another. There is more about that on the page about this site.
