Description Long

A single nail, hammered into a surface, serves as the base. The challenge is to balance several nails of equal length on the head of this nail so that they remain stable without touching the table or board. It requires skilful interlocking of the nails so that they stabilise one another and distribute the weight evenly.

Preparation

• Prepare enough sets depending on the number of participants.
• Complete sets are also available to buy commercially.

Execution

Depending on the target group, it may make sense to carry out the task individually, in pairs, or in teams.
It can also be useful to have participants create the set themselves first – for example, by sawing suitable boards, hammering in the base nail, and gathering the required number of nails.

Option 1 (set fully provided):

• Provide the necessary number of sets based on the number of participants and the chosen group arrangement (individuals, pairs, or teams). Give the task and allow 10 to 15 minutes for completion.

Option 2 (set to be created first):

• Provide the necessary materials (boards, saws, hammers, nails, and possibly protective gloves or goggles) according to the number of participants and group arrangement. Give safety instructions, assign the task, and once the sets have been completed, allow 10 to 15 minutes for the challenge itself.

Hints from experience

• This method is particularly suitable as a Turnaround activity following a very active and lively Opening phase, as it helps participants refocus and prepare for a more concentrated closing process.
• The workshop facilitator should be prepared to confidently demonstrate the solution, as it is quite common that no one in the group finds it on their own.
• One possible solution is shown in the following video: https://www.youtube.com/watch?v=NHRiN7goJ-0
