Inventions Quiz

About this test

The history of invention is far less heroic than textbooks suggest. It is made of mishandled experiments, failed products and markets stumbled upon ten years after the patent was filed. So this quiz leans as hard on original purposes as on inventors, because that is usually where the real information hides.

Bubble wrap is the perfect case. In 1957, two American engineers were trying to make textured wallpaper by sealing two plastic sheets with air bubbles trapped between them. Nobody wanted it on their walls. It took a computer company looking for a way to ship fragile machines for the material to find its market, and it has never left it since. The microwave oven follows the same script: it came from an engineer working on radar magnetrons who noticed that a snack had melted in his pocket.

There is also an uncomfortable idea to accept: most famous inventions were multiple inventions. The telephone, the light bulb, the internal combustion engine and photography were all developed by several people within months of each other, in different countries. The question is therefore not who had the idea, but who filed the patent and who managed to sell. This quiz sticks to datable facts: patents granted, first public demonstrations, market launches.

How it works

Twenty questions with four options each, from the best-known inventors to accidental discoveries, with exactly one correct answer every time. Every question rests on a datable fact — a patent, a demonstration, a launch — and never on a disputed claim of priority. The full breakdown appears at the end.
