This a very visual rope trick that will fool even most magicians, yet is very simple to perform.

You show a plain red colour rope. You tie a knot on this rope. As you pass your hand over the RED knot on the red rope, the knot changes colour and you now have a BLUE knot. The BLUE knot then changes colour to a YELLOW knot. When the YELLOW knot is opened, it is found to have blended with red rope and you now have a yellow rope on the red rope.

The rope is about 5′ in length and is made of very high quality, bright collared, soft crotchet material.
