You show 2 pcs of bamboo which are attached to each other with a bolt and nut on one end. Thru the other end a string is threaded. You pull on one end of the string and pull the rope completely thru, then you pull it again to the other side untill you are ready to do a miracle.
You now take a knife, put it between the two bamboo rods and cut the string in half. You now open both halves like a fan and the cut string can be seen on both ends. You now close the fan again, snap your fingers and the string can be pulled and is now fully restored!
We supply everything you need except for a knife. Online video-instructions are included.
