When a small bookshop in England was moving to a new location down the street, it faced a problem. How could it move its entire stock to the new spot, without spending a lot of money or closing down for long?
They put out a call for volunteers to help. Over 200 people showed up. They formed a human conveyer belt, shoulder to shoulder, 500 feet long from the stockroom of the old shop, down the sidewalk, and into the new shop.
Cafes brought tea to the volunteers, people at bus stops joined in, and in just one hour the community passed more than 2,000 books, hand to hand, to the new shop.
