When
you
hear
the
word
art
,
you
probably
think
of
paintings
in
galleries
or
____________________
in
museums
.
But
art
isn
?
t
always
inside
,
and
you
don
?
t
always
have
to
pay
to
see
it
.
In
fact
,
you
can
view
some
really
interesting
art
for
free
in
public
spaces
around
the
world
.
Public
art

just
making
a
place
look
pretty
:
it
can
change
society
.
In
Las
Palmitas
,
a
neighborhood
of
Pachuca
,
Mexico
,
residents
worked
together
with
a
street
art
group
to
paint
their
____________________
houses
in
bright
colors
.
The
result
was
an
enormous
mural
that
can
be
seen
from
miles
away
.
As
the
community
worked
together
on
the
project
,
they
noticed
how
the
art
____________________
joy
to
their
neighborhood
.
?
In
the
morning
,
you
wake
up
and
look
around
and
see
the
colors
that
surround
you
,
?
said
one
resident
.
?
It
?
s
very
pretty
.
?
Public
art
can
also
send
a
message
.
For
example
,
much
public

In
2014
,
British
artists
Paul
Cummins
and
Tom
Piper
placed
888
,
246
ceramic
poppies
on
the
ground
around
the
Tower
of
London
.
The
temporary
display
of
artwork
was
in
honor
of
the
hundred
-
year
anniversary
of
the
start
of
World
War
I
.
Each
poppy
represented
a
____________________
who
died
in
the
war
while
fighting
with
the
British
.
The
goal
was
for
visitors
to
think
about
and
remember
the
soldiers
.
After
several
months
,
the
artwork
was
____________________
____________________
,
and
the
poppies
were
sold
to
raise
money
for
charity
.
Public
art
can
also
make
people
____________________
of
a
situation
.
In
2010
,
the
Icelandic
artist
Bjargey
Ólafsdóttir
created
Red
Polar
Bear
on
the
Langjökull
____________________
in
Iceland
.
It
____________________
the
red
outline
of
a
polar
bear
on
the
snow
.
The
very
large
bear
?
80
m
by
50
m
was
made
out
of
red
food
dye
.
Ólafsdóttir
wanted
to
make
people
think
about
the
polar
bear
and
how
its
____________________
is
in
danger
because
of
global
warming
.
Of
course
,
sometimes
public
art
is
there
____________________
because
its
beauty
brings
people
pleasure
.
One
example
is
the
Floralis
Genérica
in
Buenos
Aires
,
a
____________________
metal
flower
in
a
pool
.
It
opens
every
morning
and
closes
every
evening
.
The
flower
and
the
pool
reflect
everything
around
them
.
It
?
s
an
amazing
