Rope Shape Challenges

---

Identify Quick Challenge: 1 Pentagram, 2 Heptagrams, 1 Octagram, and 1 Nonagram.

I participated (and learned) Blind Polygon in 1991 at a Project Adventure training. We all donned blindfolds before our facilitator dropped a big pile of rope (tied at the ends) somewhere in the field of play. Our first task together was to find the rope (I don't remember out strategy). Once we found it the facilitator called out (two-dimensional) geometric shapes we were challenged to form - still blindfolded (e.g., rectangle, square, equilateral triangle). To this day I remember how focused I was at listening for someone to tell me what to do. It was, and still is, a great experience to open conversations about detailed communication, listening and leadership. (NOTE: A new preference to 'unsight' participants is to simply ask them to close their eyes. This adds to conversations about integrity, trust, and choice.)

In the mid-90s I participated in a workshop lead by Sam Sikes, author of Feeding the Zircon Gorilla and Other Team Building Activities (Sam and I have since written books together). At that workshop I learned 5-Pointed Star (pentagram). Groups of five to eight players are given a long activity rope (e.g., 50 feet) tied at the ends. The group starts in a circle formation holding the ropes in both hands - the circle of rope opened as large as possible. The task (challenge) is to form two-dimensional 5-pointed star (see diagram) without anyone completely letting go of the rope - a participant's hand(s) can slide along the rope.
​
It's a great cognitive challenge, bringing to the forefront participants who live more in their logical brain. (Over the years I added 'Shooting Start' after a group solved the puzzle - "How fast can you make the 5-pointed star?" Increased risk, clear roles and responsibilities, and competitive (lower the time). NOTE: To date I've clocked groups at under five seconds.

All that being said (and you know I love diving into "all that"), I'm now playing with other gram-shapes. The first new one I tried was this heptagram (at right). It has a wonderfully simple solution, just like the pentagram: From a (rope) circle the group moves to a figure eight, then folds over the figure eight and pulls the five points (pentagram). Look at the diagram of the heptagram and discover how you can 'unfold' the lines into a figure eight. (Pull down the top point or vertex.) The main difference will be the need for seven vertex's. So, play with a group of seven to nine participants. 

The only other one I've tried is another version of a heptagram. This one took longer to solve and with all the crossing intersections our 50-foot rope shape got pretty small (tighter fit between players). When I try this one again, I'm going to go with a 100-foot rope (two 50-footers tied together). I'm guessing it will change the communication dynamics a bit? 

While researching geometric shape names I came across a couple more I want to try. How about this octagram (right)? Again, with more vertex's, I'll use a longer rope (e.g., 75 to 100 feet). Thinking through - we'll need at least eight, no more than 10 participants. NOTE: When there are more people than vertex's the 'non-point' players find a place along a line to hold the rope. They need to understand their role and responsibility just like everyone else. 

And then there's one I found I'm really excited to try - specifically when I have three groups working on the challenge. The Nonagram (I'm thinking of calling this the "No-Way-Nagram"). Each group has a 50-foot rope with nine to 12 participants. After giving the challenge (and a diagram of the nonagram), I'll let them work on it. Then, maybe 10 to 15 minutes in, I might drop some suggestions about collaborating with other groups. How they interpret collaboration is up to them. ​

Before reading on, can you see a super-easy solution (and maybe the only one), for the three groups to create the nonagram? (Pause for dramatic suspense....) Each group creates one triangle and then the three groups overlap the triangles. No-Way-Nagram! 

Let me know what you think and tell me how it goes when you try these challenges! (I'm now working on the idea of three-dimensional rope shapes??)

All the best,
