Heliumstab

The group is set up in two long rows, opposite to each other, shoulder to shoulder. All participants stretch out their index finger on which is placed a single long rod. Now the group has to lower the rod down to the ground, the rod has to be touched with all fingers at each time. At first glance, it sounds quite trivial, but in fact, it is a challenging experiment because the rod develops itself dynamic forces which only can be counteracted by teamwork and concentration.
