The Bandanna, Cup, Marble teambuilding game requires a group of 4 to 8 people to transport a marble sitting atop a cup (upside down) from point A to point B.
I once led this activity at a retreat for a group of school system volunteers (adults). There were about 30 people so I had them form into 3 groups in one of the meeting rooms. After everyone was set to go with the activity, I asked them to place their bandana-cup-marble assembly on a small table in an adjacent room SIMULTANEOUSLY. There was only one doorway and to the other room so the teams were forced to wait on each other. The table was small which forced the groups to communicate and create a plan. I had everyone circle up in their small groups and answer the following questions: What metaphorically is the bandana, cup, marble, and table relative to your job in this organization? I gave the groups 15 minutes to create a presentation, which they would be giving to the other groups. The group loved the activity and loved the discussion as well as the presentations from the other small groups.
I learned this activity from Sam Sikes, author of “Executive Marbles” and “Feeding the Zircon Gorilla”.
