Rubber Bones - Part Two

A week after we put our chicken wish bone into the jar with vinegar, it is ready to be taken out!
It felt like rubber and you could tear it easily.
The acid in the vinegar had dissolved the calcium in the bone and this had left it weak and bendy.

A 19 to 50 year old should be having 1000mg of calcium a day and a baby aged o to 6 months should have 210mg of calcium!
One cup of semi skinned milk contains 301mg of calcium, where whole milk contains 290mg.
You can also get calcium from cabbage,broccoli, Oranges and tofu.
