In 1965, American scientist Margaret Lovatt lived with a dolphin called Peter for ten weeks to try and teach him to speak English - part of a NASA-funded research project into human-animal communication. Condemned by the wider scientific community as an elaborate circus trick, Margaret's lessons with Peter remain a controversial episode in the space race between the two Cold War superpowers. Inspired by the real Dolphin House experiments, Breach's Fringe First Award-winning Tank rips history apart to explore the difficulties of bridging cultural divides, the politics behind the stories we tell, and what happens when you inject a dolphin with LSD.
