Seven compelling reasons drew 6 million (⅓ of Britain's population) to Hyde Park:
Steam hammers, telegraph, hydraulic press, nascent photography, revolvers, sewing machines—industrial future made tangible.
100,000 exhibits from 40+ nations. Indian textiles, Chinese porcelain, Canadian furs, Chilean copper—world in one building.
Working models, scientific demonstrations, design schools. Albert's vision: "promote industry, art, science."
Britain as "workshop of the world." Working-class visitors (shilling days) shared in imperial achievement.
Fountains, concerts, restaurants, carousel, first public flush toilets (827,280 paid uses!). A day out.
£186,000 profit → funded V&A, Science Museum, Natural History Museum, Royal Albert Hall, Imperial College. Trade deals signed.
Visitors returned home to invent, improve, compete. Paxton's prefab glass/iron palace itself revolutionized architecture.
Template for every Expo since. The Crystal Palace burned (1936), but the idea—progress on display—endures.
