Two weeks ago, we put a chicken bone into a jar of vinegar (with a little red food color for effect as it was almost time for halloween). This chicken bone was already cooked and our son tried to bend/break the bone before putting it into vinegar.
Two weeks later, today, we took it out of vinegar to see what happens. And it became quite flexible..You can bend it as much as you want. It was like a thick rubber!.
What happened? Vinegar absorbs/takes away the calcium in the bone leaving it bendable. This is what happens to bones when no enough calcium gets absorbed by the body. So, kids, listen to your parents and get enough calcium and exercise for your bones...
