Materials needed: sheets of paper, marking pens, tape.
A sheet of paper with the name of a person, place, or thing written on it (ie: 'Thomas Edison' or 'Giraffe') is attached to the back of each participant.
As each name is different from another, the individual participant does NOT know what person, place, or thing is attached to his or her own back; and, therefore, the participant must mill about the room asking only yes/no questions of the other participants to try to learn who is taped to his/her back.
The other participants can only answer 'yes' or 'no' to the individual's questions.
Example questions the individual participant might ask are: 'am I a basketball player?' ... 'do I live in America?'... 'am I a place?'.
