How Did a Sheet of Exercise Paper Make a Sharp Pop?

Many children who grew up in China during the 1960s and 1970s remember a folded paper popper, although its name varied by region. It required no purchase: an old sheet of exercise paper or scrap paper was enough. A rectangular sheet was folded along its centre and corners, leaving an inner flap. When one end was gripped and swung sharply down, the flap opened suddenly, moved the air and produced a crisp pop. There was no single national folding pattern, name or period of popularity.

The game often began when the first attempt made no sound. Paper that was too soft produced a dull result; loose creases stopped the inner flap from opening; and an arm lowered without sudden acceleration made only a rustle. Children pressed the folds again, tried slightly heavier paper and compared whose pop was louder. One demonstrated, another tried, and imitation created the activity without many formal rules.

A paper popper had little value as an object. It tore with use and might simply return to the scrap pile. It shows how many playthings of the period were never finished products. Ordinary material, making, failure, adjustment and comparison with friends were all part of the play.
