Icebreakers are fun, release tension and are designed for indirect interaction.
Icebreakers are not encounter sessions. When people laugh, tension decreases. Find someone who is a graduate student, owns cross-country skis, has been to Europe, wears contacts, is wild about chocolate ice cream. Information can include hobbies, hometown, major, favorite family members, five or ten year goals, favorite book, etc. Ask members to stand in the middle of the room and have them move to either side to indicate their choice.
