World's Fairs, also called universal exhibitions, are exciting events where countries from around the world come together to show off their best inventions, culture, and ideas! 🌍
These fairs last several months and happen every few years in different cities. The first World's Fair was held in 1851 in London, England, and it was called "The Great Exhibition." Each fair has a theme, like technology, culture, or the environment, and countries build amazing pavilions to attract visitors. People from all ages come to learn, enjoy, and experience fun exhibits! 🎉
