Equipment
You don't need any equipment to play that game.

Procedure
The participants stand in the shape of an "8". They all look towards their neighbour, so forming one endless line of people.

After the starting signal, they all start to walk forwards along the shape of the "8". In the center point of the shape, they have to take care not to collide with the other people there. Once started, the group has to move faster and faster, but avoiding collisions in the middle. How fast are they able to go?
