An emulsion is a mixture of two or more liquids that are normally immiscible (un-blendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion is used when both the dispersed and the continuous phase are liquid. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, milk, and some cutting fluids for metal working. The photo-sensitive side of photographic film is an example of a colloid.
The word "emulsion" comes from the Latin word for "to milk", milk being (among other things) an emulsion of milk fat and water. types of emulsion: 1.o/w emulsion oil is dispersed phase while water is dispersion media. 2.w/o emulsion water is dispersed phase while oil is external phase 3.multiple emulsion 3(a).w/o/w 3(b).o/w/o
Emulsions, being liquid, do not exhibit a static internal structure; the droplets dispersed in the liquid matrix (the “dispersion medium”) are assumed to be statistically distributed.

Where do we go?
Now all the late night bars have closed?
And all our friends have turned to shadows
People come and people go
People come and people go
In the blink of an eye
We're all gonna die
So why are we waiting for tomorrow?
Why are we drowning with our sorrows?
People come and people go
People come and people go
Down by the sea, remember me
'Cause for that instant I was free then
Out on the sand with no demands
No one to tell us where to be
Emily Snow
Surely I know
That was all long ago and far away
But I remember my promise to you, Emily Snow
Though people come and people go
People come and people go
People come and people go, I know
I know, I know, Emily Snow
Down by the sea, remember me
'Cause for that instant I was free then
Out on the sand with no demands
No one to tell us where to be
Emily Snow
Surely I know
That was all long ago and far away
But I remember my promise to you, Emily Snow
People come and people go
People come and people go
People come and people go, I know
