The group of participants will be divided into two teams, where the number of participants is equal between the teams.

These two teams will be the trains and the participants will be the wagons.

A railway will be drawn on the floor, in which there will be a square for each participant and an empty square in the middle.

The goal is for a train to change with the place. The rules are as follows:

1. Two wagons can not move at the same time. 2. Only one person can be in each wagon. 3. Wagon cannot step back. 4. Wagons cannot be outside the railway. 5. If the rules were broken, the exercise starts again. 6. In case of a mistake, the person who was first goes to the end.
