HOW TO MAKE A SPY-SCOPE???

Let's make a spy-scope!! A spy-scope works like a mini telescope. It is very easy to carry anywhere!!


Materials:
2 magnifying glasses


INSTRUCTIONS
Hold the each magnifying glass in one hand and line them up.
Now focus them on an object which is a bit far away. You may have to rotate the magnifying glasses or move them forth or back.


Observe: The object comes in focus but will be upside down!Why?The object your eyes retina see's is also upside down!! But the brain flips it back to it original position!Your spy-scope works like your eye but is not able to turn them as they don't have a brain!!!!
