These cool science experiments create "funny bones" that can bend. Bones have two main substances calcium carbonate and collagen. Calcium carbonate, (calcite) gives our bones strength. Collagen is a light and flexible material. These two materials combine to give us and other land animals strong bones that are lightweight.
When bones are placed in an acid a chemical reaction occurs. Tiny bubbles of carbon dioxide form as the acid reacts with the calcium carbonate. The collagen in bones is left behind as the calcium carbonate dissolves. In this experiment you will be testing a variety of chicken bones to see how they react to being left in a bowl of vinegar for up to 10 days.
