fascinating manipulative toys made from folded
strips of paper which, when flexed, change shape
and pattern in remarkable ways. The way flexagons
change shape and pattern depends on the shape of
the segments the strip is divided into.
Hexaflexagon strips are divided into equilateral
triangles and tetraflexagon strips into
are flexagons where the strip of paper is divided
into segments in the shape of right angle
isosceles triangles. This simple change gives
silverflrexagons quite extraordinary properties
and greatly increases the variety of shapes and
patterns thry will flex into. This book explains
many of the most interesting silverflexagons,
maps them completely, and gives hints for
The Flexatube is probably
the greatest paper puzzle ever invented. It is
not technically a silverflexagon but it is very
like one and equally interesting to play with.
This book gives seven and a half distinct
solutions and shows how to vary the puzzle to
make it more challenging to solve by combining
Flexatubes into stacks, chains and mats.
