How Did an Exercise-Book Page Become a Paper Plane?

A paper plane was one of the easiest toys to make without actually buying a toy. A used exercise-book page, scrap paper or a sheet torn from a notebook could be folded down the centre, narrowed at the nose and opened into two wings, then taken straight into a corridor, courtyard or school ground.

The fun often began after the first flight. If the nose was too light, the plane might float badly; if the wings were uneven, it could veer to one side. Children would flatten a wing tip, sharpen the nose or change a fold, then throw it again. The game quickly became a small experiment: whose plane flew furthest, whose stayed straight, and whose could glide the length of a corridor.

That kind of play suited households where purpose-made toys were not always plentiful. Paper was ordinary and reusable, so an old sheet could become a new object within minutes. What mattered was not its price but how quickly material, hands and a few companions could turn it into a complete game.
