How to make a chicken bone bendy!
To do this fantastic experiment, you will need:
- A clean, empty, coffee jar.
- Two large jars of white vinegar. (Malt vinegar, will not work!)
- A clean chicken bone leg, you need this, otherwise it will not work.
How do accomplish your bendy bones:
You firstly need to clean your coffee jar and make sure you keep the lid.
Secondly, you need to eat all the chicken off of the bone and wash and clean the chicken bone.
After, when you have washed everything up, fill the coffee jar up with white vinegar.
Next, carefully place the bone into the vinegar.
Screw the lid on tightly, and place in a dry, cool place.
You have to wait Two weeks in all but once one week has past replace the vinegar before then waiting a further week.
After two weeks, cover your nose and unscrew the top. Take out the bone.
Bend it! Squeeze it! Then dispose of it! Do NOT eat it! And do NOT taste it!
Why does it work?
Vinegar is a mild acid on the ph scale, however is strong enough to dissolve calcium when left in it for a significant amount of time. Bones are made up of calcium and that is why vinegar can dissolve it easily, as a result the more milk you drink the stronger your bones will be, therefore they will be stronger and would be harder to dissolve. Oxygen and calcium in the bone mix together to create calcium carbonate that is a compound (CaCO3). Did you know if you left your chicken bone out in the air and oxygen again you would find it goes hard again.
