Table
Teaser is four puzzles in one. Before you begin folding it, you
already have a handy book-marker of two colours. First you have
to fold it to make a square coaster with only one colour showing.
The magnets hold it firmly in place. Then try to make it change
to the other colour without undoing the magnets - not so easy! Now
undo the magnets and refold it to make a napkin ring. Finally make
the napkin ring reverse colour without parting the magnets. This
interesting and unusual puzzle will appeal to all enquiring minds,
and makes a novel talking point at the dinner table.
This
original design is an adaption of a discovery by the mathematician
Arthur Stone, called a flexitube. (He also invented the flexagon,
see our Crafty Coaster and Kaleidoscope).
In our version, the flexitube corresponds to the napkin ring, but
the colouring pattern of the triangles allows a second method of
folding to make a flattened form which can be used as a coaster.
As far as we are aware, this added property of the flexitube is
an original discovery. Another added feature is the use of magnetic
plates to fasten the ends, rather than glueing them together as
in most paper models. It would not otherwise be possible to fold
both forms from the same strip.
Table
Teaser is of interest to recreational mathematicians and puzzlers.
It is strongly constructed using ribbon, magnets and 32 wooden triangles.
Instructions are included.
