The group will need to work well as a team.
Endeavouring to build a tower of crates, two team members will have to use good balance to stay on top of it as it gets higher.
This will test their co-ordination, common sense, agility and teamwork skills. They will learn how to belay, as they will control the ropes; as well as tackle the task itself. It is very rewarding in terms of self-achievement and confidence building. Participants can choose how high they go and so set their own challenge; or compete to get the highest tower.
‘Complications’ can be added to the tasks to make it harder for braver groups!
