Question: Very interesting the specialised shape of this artefact object. Indeed it moves for 25 seconds when touched. My question is if they had stable, flat surfaces to put the rock on. I think maybe you try the same at a slate palette, or a similar natural surface to see the moving of the artefact? It 's not that I'm not convinced of the principle- stone age people are very much the same as we are!- but how does this work on a natural surface?
i have several 'bobblehead' creatures...seals,and birds...i have placed them in flowing rivers/streams...or at the edge of the ocean and noted they 'wabble' with the flow of the water...they look rather alive when seen moving around seemingly on their own.
