This is a traditional Scout lashings game which might date back to Baden-Powell himself. It practices Scoutcraft (lashings) as well as cooperation and problem solving.
Pioneering Troop Program Feature
These instructions are for a pot and towel drying rack. There is a small picture of a similar gadget in the Scouts BSA handbook.
This is a gadget which was shown to us at a recent Roundtable. It uses lashings to make a handwashing station from straight sticks and an empty gallon milk jug.
The Pioneering feature teaches Scouts how to build structures and gadgets using rope, spars, creativity, and knot skills.
This book was recommended a few years ago when I went to Cub Scout BALOO training. I am not a “knot person”. I can watch someone do a knot and repeat it, but an hour later it is forgotten.
