Children's perplexed reactions to a Sony Walkman have been caught on camera, with the majority frustrated at operating clunky buttons over a touch screen. Los Angeles-based filmmakers Benny and Rafi Fine asked volunteers aged six to 13 to guess what the bulky device was, with suggestions including a 'walkie-talkie' or 'boombox'. 'What is this?' one nine-year-old girl quizzed as she investigated the Eighties-era cassette player, while another exclaimed 'I'm not going to give up, I'm a survivor,' as she determinedly tried to figure out how it worked.
