Acid Attack

This experiment shows you what acid can do to bones. Bones just like teeth contain a lot of calcium and minerals. In your mouth the bacteria coat your teeth in acid too.

Try this fun experiment at home (with the help of mom and dad of course!)


You will need:

• 2 clean chicken bones
• 1 jar
• 1 bottle of vinegar

What to do:

Pour several inches of vinegar into the jar. Soak the clean chicken bones in the vinegar overnight.

What happened to the bones? Are they just as hard or are they softer? The acid dissolves and removes the calcium and minerals out of the bones to make them soft. Just like the bacteria and plaque in your mouth makes your teeth soft too. Throw away or better yet compost the bones!
