Small Inventions that Made a Big Difference

Small inventions - modest yet essential, diminutive in size and humble in stature - are an essential component of every element of everyday life.

Fifty little objects of fascination, each concealing an unexpected history of innovation, are explored in Small Inventions that Made a Big Difference. From the ever-present (teabags) to the barely visible (ball bearings) and from the absolutely necessary (toilet paper) to the never-knew-you-needed-it (Post-its), science writer and comedian Helen Pilcher will guide you through the wonderful world of tiny examples of ingenuity.
