Playing with virtual critters Jurassic Period on Living Timeline! This is an exhibit all about what has happened during Earth's long history. It starts at 6 billion years ago outside the entrance of At-Bristol and finishes here arriving at a planet teeming with interactive life! Living Timeline is part of At-Bristol science centre's latest hands-on exhibition Our World - no more waste. Check out our other video to see how it was made. The exhibition is supported by the SITA Trust.
