Bendy Bones Experiment
Turn your chicken dinner scraps into a fantastic science experiment which turns brittle chicken bones into pliable ones. This experiment is super easy to execute. The hardest part of it all will be waiting patiently to see the results, which takes three days. While you are waiting, have the kids take a guess as to what will happen to the bone, then enjoy the discovery.

How It Is Done
You can see how the bone has a bendable and rubbery property. Discuss why you think this is so. Human and animal bones are hard because they contain the mineral called calcium. The vinegar is a mild acid, so when the bone is submerged in the vinegar, the vinegar breaks the bone down, dissolving the calcium and making it rubbery and bendable.
