Fun Team Challenge to Build Trust & Cooperation Marshmallow River
Fun Team Challenge to Build Trust & Cooperation Marshmallow River is a team reflection exercise for reflection and learning: it helps participants reflect on experience and turn observations into learning.
How to run it
- In advance, randomly distribute dozens of ‘marshmallows’ between two lines spaced about 10-15 metres apart.
- Place many ‘marshmallows’ close enough so that people can step from one to another easily.
- Gather your group behind a line identified as the Start zone.
- Challenge your group to traverse the area between the two lines by stepping only on the marshmallows.
- Invite individuals to traverse the area first, using any path they choose.
- If a person happens to touch the area outside of the marshmallows, invite them to restart.
- Next, invite two people to cross together while keeping physical contact at all times.
- Again, if someone touches the ‘no-go’ zone, invite the pair to restart.
- Marshmallow River Fun team challenge to build trust & collaborative problem-solving.
