No these are smart. The shot they take, will be told, to shoot it, and the Turkish coffee, not sure if you aware, is so strong, almost you cannot detect the pure cap until it too late. We have hidden camera of the exam, and 7 mates will be taking shooters minute before the exam, as told is brain power during our cram time. A waitress will serve it to be foolish. So it will look more legitimate.
Already, we have finished one test subject on this, and told him to shoot it. He was on toilet 3 hour.
