1t Is now almost certdlu tho0 Aidui~
air viii soon be put on the market a.
very moo era.e prices. The practical
householder, therefore, Is already
beginning to ask questions.
GOT what use will 1t be to me-" he
queries. "Why should l pay money
for cansof air, liquid or other! IL Il
very curious and interesting no dou OF,
hut what can do with it? And len I
It dangerous stuff, anyhow, to nave
about the house,"
To answer these very natural cues
and in plain language. Is the purpose
of this article.
ONLY home uses will be considered,
and even of these scarcely half can be
Indicated II there is any limit to the
intimate possibilities of liquid air the
writer hasn't yet discovered IT.
First, how will 1t be supplied, now
long can it be kept. and Is IL SAFE u
handle?
like milk or seltzer water, In protect-
ed cans containing any desired guam
titv. from a quart or two up to twenty
mr. thirty gallons. The style OF the
cans will doubtless vary. Inc Simplest
are nothing more than tin cylinders,
closed st the bottom but open at the
top and heavily felted.
In this liquid sir can be kept about
twenty-four hours. You can dip IL
ont "a wanted with an ordinary long
handled dipper. If, however, says the
New York World. you should drop
tho dippar just sitter using it would
an like thin glass when it struck
the floor. With ladle of copper or
aluminium this little incident could
not occur, as these metals are not made
brittle bv cold.
Py the use of more elaborate YES
seIs-some of which have already been
tested and patented-the liquid air
can be kept for a number OF days.
From these it is drawn off by sort OF
rpipot. It can be cent by rail and de-
livered at distant points.
LIQUID air is as safe to handle as
boiling water, and req uires about the
same precautions. Here extremes
meet. Intense cold burns Ike heat,
and LIQUID air has even been used to
cauterize ulcers.
Yet YOU need not fear to touch 1t.
You may thrust your hand into basin
Of it with perfect safety, just as you
NAV touch hot iron with your moisten-
ed finger. provided the hand is instant
Nv withdrawn. II spilled on your
clothes It will not harm even the finest
fabrics.
But never venture to put I1qu1o air
In your mouth-if you wish to live.
And in taking up dish containing IL
use 8 handkerchief or holder of some
sort. exactly as If it were hot.
II another respect liquid air is like
boiling water. 1t must not he confined.
Plug up your teakettle aud it will soon
burst. II the plugged kettle contained
LIQUID air It would do the same thing
oven though set upon q block of ice, for
this strange stuff is always boiling and
Won can't prevent 1t.
Be careful also not to wet cotton
waste or any other loose, combustible
with this liquid. Such
mixture. is violently explosive. though
only until the liquid gas has evaporat-
ed: and it will not explode unless fire
is put to 1t.
These things remembered liquid air
il more innocent than spriug water. II
q canful were upset on your parlor car
pet there would be no harm done
And now, assuming that two-Ral-
lon can has been delivered atyour door,
What can you do with it?
Of course the most obvious use Is for
cooling things-any sort OF refr1gera-
