There are innumerable objects on the earth, and they are characterized by so many aspects.
One important method to recognize an object is to know its specification factors like size,weight,material,smell,and so on.
In this quiz,each person first images one object and makes its catalog spec list. And then the other person tries to guess the object only from those hints.
The answer will not be single.
If there is a large difference between the number of answers by changing the number of hints, that may be interesting.
