Rubber Chicken Bone
WHAT YOU NEED: uncooked chicken bone or wishbone, clean and empty glass jar with lid, white vinegar.
WHAT TO DO:
1. Clean the bone thoroughly and let dry overnight.
2. Place the bone in the jar and add enough vinegar to cover the bone.
3. Secure the lid and let the jar stand undisturbed for seven days.
WHAT HAPPENS: The bone becomes soft and rubbery. It can be twisted, and, in some cases, tied in a knot.
WHY IT WORKS: The vinegar (acetic acid) dissolves the calcium from the bone, leaving it soft and bendable.
