On 25 May 1986, 6.5 million people did the impossible; they joined hands to form the world’s longest human chain, from New York to Los Angeles. But far from being a simple stunt, Hands Across America was raising money to fight hunger and homelessness in the world’s richest country. Did it succeed? Aleks Krotoski was 11 years old when she stood in the sunshine between her mother and a stranger and held their hands for those 15 minutes 35 years ago. She speaks with the organisers, the people who participated, and the people who received the donations, and discovers that Hands Across America didn’t just feed the hungry, but led the social networking revolution as well.
