Museums across Scotland have taken part and you can too
Work has been ongoing to find objects which capture the history of the world.
The BBC, British Museum and museums across the country have been working together and you can get involved.
Objects have been selected by the museums which tell stories and make connections locally and across the globe.
The first set of objects were unveiled on Monday, 18 January.
The artefacts tell the story of their makers, different owners, the journeys they have undergone and the changes in meaning or function across time and space.
