http://en.wikipedia.org/wiki/Adulterant
a short and enough list
I have made an investigatory project on study of adulterants on food stuffs.
I wanted to know what all possible questions can the examiner ask on this project.
The first and foremost ques (for food adulteration) is:
"Was the biscuit your school gave me to eat poisoned?"
Answer: (politely)
"Of course not"
Question:
"Was there something else in it?"
Answer: (Innocently)
"Nothing much, Sir. Just a few pills of horse laxative"
Question: "Are the toilets in ur school clean?"
Answer: (Apologetically)
"Don't know, Sir. Depends on the amount of laxative given to the other external examiners"
PS
NOT TO BE TAKEN SERIOUSLY
