This is a trick I have been using for 30 + years. I do not know where it came from but it is a really great trick which I have honed with a strong routine that is great for adults and children.
For those in "the know" this is, Equal Unequal Ropes with a good storyline.
Needs a little handling, but well worth the effort.
Made with Red Magicians Rope and individually bound.
Comes in a plastic container.
