Our science experiment for the week was to decalcify some bones.
We roasted a chicken one night, covered the bones with vinegar in a jar and waited.
5 days later- the bones were inspected for changes. Besides darkening, they were rubbery and easily breakable. The acid in the vinegar changes the hardness of the bones and we could easily break them and see the marrow inside.
Harper wouldn't touch it with her bare hands
Pretty exciting stuff
