Our plates have the best retirements! After being on a🔭, they get to go via a ferry to the Orkney Science Fest with Anne-Marie Weijmans, meet some schoolchildren, and spend the rest of their days inspiring people
Anne-Marie is holding a large aluminum circle with many holes and markings. She is standing on a ferry with blue seas and blue skies.
