It is an optical instrument that forms beautiful 
patterns .  It contains two mirrors which meet at an angle 
of 60 degrees. Light from coloured objects placed near the 
mirrors bounces between them to form several reflections. 
The most fascinating aspect about the kaleidoscope is that 
you never get the same pattern twice. Designers of wall 
papers and fabrics make use of this instrument to get ideas 
for new patterns. 
YOU REQUIRE 
1. two rectangular mirrors of the same size (8"long 
&2"wide )
2. one cardboard sheet of the same size as the mirrors 
3. tape 
4. tracing paper 
5. transparent plastic paper 
6. small pieces of bangles 
7. glue
WHAT TO DO 
1. take two rectangular strips of mirrors identical in size 
about 8""long and 2"wide . Take one cardboard piece of the 
same size as the mirror strips. Join the mirrors and the 
cardboard together to form a long triangular tube. The 
silvered sides of the mirrors should face inward. The 
angles between them will be 60 degree. This angle will form 
symmetrical  patterns.
Cut a piece of tracing paper or plastic paper to fit over 
one end of the triangular tube and glue or tape it in 
place. 
2. take about 7-8 pieces of bangles with different colours. 
Put these coloured pieces in the tube. Then hold the tube 
upright so that the pieces rest on the tracing paper. 
3. Look down into the tube and see the pattern formed. The 
end of the triangular tube near the eye can be closed by a 
transparent plastic sheet or glass sheet. The pattern will 
consist of 6 identical sections. Shake the kaleidoscope to 
change the patterns.
