How do mirrors actually work?
Why do mirrors flip faces horizontally but not vertically? James May explains, with the help of a very childish prank.
A mirror is made from a sheet of glass with reflective material applied to one side. It is like an old fashioned transparency photograph viewed the wrong way around.
