Requirements

Two small mirrors
One long cardboard or plastic tube
One small hacksaw
Glue


Steps

Take a cardboard tube and two small mirrors. Use a small hacksaw to cut a section near each end of the tube. First make a horizontal cut to about ¾ of the diameter of the tube.
Now cut the tube at 45 degree at 2 places. Use 45 degree set-square for guidance while making these cuts.

Glue the mirror in places where the sloping cuts have been made.The silvered surfaces of the mirror should face each other so that light passes through the instrument .
