Today’s experiments involve breaks in the knots.
The examples below show one through five breaks in the Celtic knot band and its circular counterpart. The results are separate knots all around.

The examples below show one through five breaks along one edge in the Celtic knot band and its circular counterpart (the outer edge). The results are knots intertwined with their two neighbors.

The examples below show one through five breaks along one edge in the Celtic knot band and its circular counterpart (the inner edge). The results are knots intertwined with their neighbors.

The examples below show one through five breaks alternating along both edges in the Celtic knot band and its circular counterpart (the outer and inner edges). The results are two intertwined knots, one revolving clockwise and one revolving counterclockwise.

What sort of experiment will I run tomorrow? Come back tomorrow and find out!
