Rubber Bone

Planning to make fried chicken? Take out a few bones beforehand. They’ll make for a cool project!

Make this fun science project with white vinegar and an uncooked chicken bone.

Try and prank your friends. Ask them to touch a “normal” bone. They’ll be amazed when it bends like rubber!



  1. Clean the bone thoroughly and let it dry overnight.
  2. Place it in the jar and add enough vinegar to cover it.
  3. Secure the lid and let the jar stand undisturbed for seven days.


The bone becomes soft and rubbery. You can twist it and, in some cases, tie it in a knot. The vinegar (acetic acid) dissolves the calcium in the bone, leaving a soft and bendable.
