You can use vinegar to remove the calcium in chicken bones to make them rubbery. This is a simple project that illustrates what would happen to your own bones if the calcium in them is used more quickly than it is replaced.

Make Rubber Chicken Bones

  1. Try to bend a chicken bone without breaking it. Get a sense of how strong the bone is.

     

  2. Soak chicken bones in vinegar.

     

  3. Check on the bones after a few hours and days to see how easy they are to bend.

     

  4. When you are done soaking the bones, you can remove them from the vinegar, rinse them in water and allow them to dry.

How It Works

The acetic acid in the vinegar reacts with the calcium in the chicken bones. This weakens them, causing them to become soft and rubbery, as if they had come from a rubber chicken.

What Rubber Chicken Bones Mean for You

The calcium in your bones is what makes them hard and strong. As you age, you may deplete the calcium faster than you replace it. If too much calcium is lost from your bones, they may become brittle and susceptible to breaking. Exercizing and eating a diet that includes calcium-rich foods can help prevent this from happening.
