What does chalk rock look like?
It taste similar to the old chalk that teachers use on a chalk board at school. I know because I use to eat it as a child in school. I would actually take it from the school board and secretly eat it. Whenever I would smell the dust from the chalkboard at school it would immediately start an overwhelming crave to eat the chalk. For some reason it satisfied a deep crave that I was experiencing during parts of my childhood. I also liked the real white chalk in the earth, It is soooooo good and how I know is because my mother let me taste it as a child. She would literally go or have friends go out into chalk hills to find the earth's chalk mainly when she was pregnant. It's quite amazing because I am now 41 years old and still have those same cravings.
