Mirror Craft

This setup consists of a plane mirror, a long curved metal tube and a pair of glasses through which the mirror
is viewed. When viewed through the glasses
only the image of the metal pipe
in the mirror can be seen. Looking at the image in the mirror, you need to follow the pipe without touching the metal
pipe with your hand.
When you touch the metal tube, the electrical circuit is completed
sound and light signals are heard. Here, since the image in the mirror is inverted
, eye-brain-hand coordination is mistaken and it becomes difficult to follow
by hand
