This experiment simulates an acid attack on bones (bones are rich with calcium, just like your teeth).
What you'll need:
• 2 clean chicken bones
• 1 container
• 1 bottle of white vinegar
What to do:
Pour several inches of vinegar into the container. Soak the clean chicken bones in the vinegar overnight.
What will happen:
Check out the bones after they've soaked in the vinegar overnight. Are they softer or harder? How do you think this relates to acid attacking teeth?
Be sure to throw the bones away after you have finished.
