Necklace:
"Necklace flexibility is a function of angular tensions
and not of the compressional islands or beads. Its relative
flexibility decreases as beads are progressively
removed. When the numbers of beads are odd the waves
in the necklace are blocked; when the number is even
the waves are continuous.
"When the number of beads is reduced to six, continuous
wave flexibility is permitted. When the number of beads
is reduced to five the waves are blocked so the necklace
is flexible. When reduced to four beads the necklace can
be draped over human shoulders; one “V” in front and one
“V” in back. When the beads of the necklace are reduced
to three all flexibility ceases. Each angle is stabilized
by the opposite side, exercising its push-pull effectiveness
upon the two lever-ends of the angle’s adjacent sides, as
would a pair of scissors be held in fixed opening by a
pencil with the pencil’s two ends tied respectively to
the two finger circle terminals of the scissors. (Drawing.)
"If we take out one more bead the scissors become closed;
There is no opening or area between them. The opening
