this is the most amazing rotating paper model . you require A4 size paper, a scale and a
sketch pen. take A4 size paper and fold it into half and then fold a triangle. tear off
the rectangular strip and you will get a big rectangle . where the length would be double
that of the width. there will be 2 squares side by side. fold the mid line along the
length and both the edges along the mid line to get a long doubled up parallel strip. this
strip has to be folded into 8 equal parts. fold the edges to the mid line to get the
quarters and then the edges to the quarter line to get the 1/8ths then take one edge
and crease to one fold to get the quarter lines this way you will divide the strip into
8 equal parts. then take the strip, fold this into half with the open ends exposed. mark
all the 4 middle points to make a diamond shape or a rhombus. then mark the opposite
corners or the 2 diagonals . and this shape looks like a horoscope. easy to remember.
make another similar shape on the other side. now with the scale crease very clearly all
the ten slant lines. 5 to one side and 5 to the other. this will be the final crease model.
with the scale tear off one section. take this end and tuck it in the pocket of the
opposite end. we have tore one and tucked one so we have got rid of two and only 6 sections
remain now. with these 6 sections we will make a very nice prismatic shape. a kind of
a triangular roof. this is a triangular roof. and you can see that there are half diamonds
on both the edges. fold these half diamonds inside first in the first section then fold
half diamonds in the second one and finally on the third one. having folded the half diamonds
you will see a kind of hexagonal shape with petals on the top and the bottom. crease these
petals inwards and flexagon is almost ready now. you can rotate it. its amazing that you
can rotate paper without tearing it. its a great surprise. you can also make a food chain.
draw insects, insects are eaten by the frogs and frogs are eaten by the snakes, snakes
are eaten by the eagles. this is a very nice food chain
