It is known that
spies of the old days frequently communicated
to their contacts using special inks which
would only become visible under certain
conditions, for instance, when the paper is
moisted with water. But since the world
entered the Internet era, one may ponder just
how many invisible ink specialists have been
retrenched from the spy agencies, and what
kind of new careers they are going to
embrace.
In China’s southern
city Guangzhou, there is a high school. In
the school, all the students are wearing blue
jumper uniforms in the winter. The jumpers
have a plain and boring appeal, and that,
presumably, serves the purpose of keeping the
students from being distracted to each
other's looks. But what the school authority
had not expected is that the students become
attracted to their own appearances.
A few days ago, when
some students took their physical training
course in the open, a gust of clouds and mist
brushed over the school playground. As the
fine rain wetted some students’ blue
jumpers, the naked truth was revealed. The
jumpers are, in fact, not so plain and boring
but in the most flamboyant fashion with the
images of naked women all over. That effetely
transformed students into walking porn
billboards.

School uniform with
the images of seemingly naked ladies
While some students
felt dismayed at being a porn promoter,
others were excited. Those who had not been
graced with the obscene figures deliberately
wetted their jumpers to get a close contact
with the naked ladies. It is said that for a
certain length of time wetting one's own
jumpers became fashionable sports among the
students.
As for who embedded
those images in the uniforms, it is anyone’s
guess. Maybe some retrenched spies with
expertise in invisible ink writing have
discovered a new path to their career success
that is to work as a double agent between
textile and porn industries.
