Don’t throw away all your turkey bones after dinner! Save a few to try this cool bending bones experiment. (It also works with chicken bones for anytime of year.) Gather a couple of pint jars (with lids), and some vinegar.
- First, wash the bones off until they are clean of all the meat. Let the kids try to bend them (or break them) and note how strong they are.
- Put a bone in each jar. Cover one bone up with water and the other bone with vinegar. Make sure to label the jars so you keep track of which is which. Now you just let it sit for at least a week.
- Carefully remove the bones and rinse them off with water. Let the kids try to bend them again and watch what happens!
The bones will bend. The vinegar reacts with the calcium carbonate in the bones, resulting in tiny bubbles that rise to the surface. These bubbles are the carbon leaving the bone. Essentially, the calcium from the bones is being taken out. Calcium gives bones strength, and without it, the bones can be bent right in half.
Now that you’ve seen what will happen if your bones become calcium deficient, go drink a glass of milk!!
