At hairdresser's

You noticed, at hairdresser's or at home, that your reflection in the mirror is reversed. When you raise your right hand your reflection in the mirror raises the left hand. Due to everyday use of mirrors we have got used to this fact.

What could be done to make the reflection non - reversed? A set of two mirrors placed at a right angle to each other allows us to see the image which is not reversed.

Try to comb your hair in such a modified mirror!
