It has taken fifteen questions to get the answer that this was an accidental suicide, brought about by an attempt at self-doctoring at home. This is why the ‘three-questions-only’ rule would render this divination method valueless. Paper and pen or pencil are a must, because you’ve got to keep track of what you’ve asked the stones. A major drawback of this divination method is, it’s like trying to get answers out of your most close-mouthed relative, or cross-examining a hostile witness in court. If you enjoy badgering the reluctant, and like the process-of-elimination way of getting at the truth, bit by bit, then this divination tool might be your cup of tea—just don’t brew it from plants you don’t know.

EXERCISES:
1.) Devise a list of five questions for which you know the answer is yes, and another five questions for which you know the answer is no. Record the answers you get for each question. Did the Yes-and-No stones respond accurately?
2.) Devise a list of five yes-or-no questions for which you don’t know the answer. Record the answer you get for each one. Then if you can, try and research the facts behind each of these questions, make a note of whether the answer, be it yes, no or maybe/wrong question, was the accurate one.
3.) Ask the Yes-and-No stones about some old, unsolved mystery, one of which you may never discover the truth, like a famous, unsolved murder case. Record the answers you receive. Given your experience with the first two exercises, how confident are you that the answers to this question are true? If at some point in the future new evidence comes to light, compare it to your list of questions and answers; how accurate were the stones?
