Twenty Questions
 

The goal is to guess what the OP is thinking of, within 20 questions.

Starting rule set:[LIST=1][*]The original poster will state the general type (for the item thought of): animal, vegetable, mineral, or mixed (to be used only when the object is quite mixed). [*]Yes or No are the main answers. The OP will try to stick with those without explanation.[*]Questions will be taken in turn. i.e. The second question may not be asked until the first is answered.[*]If the answer is "yes", the asker of that question gets to ask the next question. [*]The asker must mark their post with the question number.[*]There maybe a 21st question of "Is it....", provided that the 20th question was answered "yes".[*]If it is successfully guessed, the one that got it gets to think up the next item.[*]Except 'point of order' posts, please no side discussions.[/LIST]

First item:

[FONT="System"][SIZE="3"][COLOR="Blue"]Mineral[/COLOR][/SIZE][/FONT]

Is it above 5 on the Mohs hardness scale?

Answer to question 1:
Yes and no
(you may ask the next question)

[points of clarification: The "animal, vegetable, mineral" starter does not mean that it is a live animal, a growing plant, or a hunk of rock. They could mean: a wool jumper, a paperback book, and the Empire State Building

Since the current object it question has parts that are hard and some that are not, the yes/no answer.]

Does each person get 20 questions, or is it 20 questions total for everyone?

You can't ask that yet.
