A useful tool

I MADE THIS PROJECT IN 7TH CLASS.IT WAS A AWESOME PROJECT MY FIRST PROJECT OF MY LIFE.I EXPERIENCED PROJECT MAKING AT THAT TIME.IT IS A THING WHICH CAN WORK AS A INSTRUMENT TO SEE THINGS IN THE FORWARD DIRECTION AS WELL AS IN BACKWARD DIRECTION.ITS USED IN TANKS TO SEE THERE ENEMY FROM INSIDE BOTH IN FORWARD AND BACKWARD DIRECTION.IT IS ALSO USED IN SUBMARINES .IT CAN BE VERY HELPFUL IN BATTLEFIELDS TO KEEP IN CHECK OF ENEMY.

TO MAKE THIS FIRST I COLLECTED DATA FROM MY TEACHERS THEN I CONSULTED A BOOK ON SCIENCE PROJECT AND THEN WITH THE HELP OF MY FAMILY I STARTED MY PROJECT.I NEEDED A MIRROR FOR IT A PIECE OF THERMOCOL OR WOOD.THE MIRROR WAS TO BE PLACED AT AN ANGLE OF 45DEGREE AND TWO MIRRORS WERE REQUIRED.THE INSTRUMENT HAD TO IN Z SHAPE AND SHOULD BE A CUBOID.

IT IS TO LIKE A PIPE Z WITH TWO HOLES ONE FOR ENTRY AND ONE FOR EXIT.THE MIRROR HAS TO BE PLACED IN OPPOSITE DIRECTION AT THE ENTRANCE AND EXIT.SO THAT AS WE SEE FROM THE BOTTOM MIRROR WE GET A LOOK OF THE FRONT FROM THE UPPER MIRROR.THE THERMOCOL OR THE WOOD CAN BE PAINTED AND CAN ALSO BE COVERED FROM A BEAUTIFUL PAPER COVER.

THE DIFFICU7LT PART IS TO PLACE THE MIRROR IN THE THERMOCOL .U SHOULD BE VERY CAREFUL A BAD PLACEMENT WILL LEAD TO WASTE OF THE PROJECT.

Barry's Response - Thanks Gaurav. Are you sure this is not a periscope in the description? That's what it sounds like to me.
