The folding fan was invented in Japan. In 988 a Japanese monk presented folding fans to the Chinese emperor, and the Chinese long called them 'Japanese fans'. Portuguese traders later brought them to Europe, where Spain made them famous.

Paper
Invention

Paper

📍 Northern China (Gansu to Luoyang)

Invention

Aerosol spray can

📍 Oslo, Norway

Norwegian chemical engineer Erik Rotheim of Oslo applied for the first aerosol spray can patent in 1926. Americans later made spray cans famous with WWII 'bug bombs' that sprayed insecticide against malaria mosquitoes.

Invention

Cat's eye (road reflector)

📍 Halifax, England

Cat's eyes were invented by Percy Shaw of Halifax, England, who patented them in 1934 and named them after a cat's eyeshine. Wartime blackouts showed their value and helped spread them across British roads.

📍 Buenos Aires, Argentina

The first feature-length cartoon wasn't Snow White (1937) but El Apóstol, made in Buenos Aires in 1917 by Quirino Cristiani from 58,000 frames of cut-out animation. Its only copy was lost in a 1926 studio fire.

Panama hat
Invention

Panama hat

📍 Ecuador (Montecristi to Cuenca)
