You Are: Home > Activities > Fun experiments > Bendable chicken bones
You can make chicken bones so soft that you can bend them!
Put a clean wishbone or leg bone into a jar and completely cover it with vinegar. Leave the chicken bone there for seven days.
The bone will go so soft that you can twist it into a knot!
Minerals in the bone make it strong and rigid. The vinegar takes away some of the minerals and the bone softens.
