The Liquid Air
Entertainment.

there was seat there was a person
and where there was person there
was someone we'll pleased. A lecture
on liquid air was the attraction. The
platform had ON it tables loaded with
apparatus for the demonstration of
the wonders of this new fluid Pro-
fessor Patty of CHICAGO gave the lee
ture and performed the various exper-
iments. He had the interest of the
audience from the start. His manner
was affable and his delivery good
Professor Patty first went a little
into the history of liquid air. He
told how in 1923 nitrogen and oxygen
had been separated and nitrogen had
been liquified. To Charles F. Trip
pier may be ascribed the discovery of
liquid air. He it was. who first sent
the air through the tanks and tubes.
applied to it mighty pressure and
brought it down to a temperature OF
312 degrees below zero where it liqui
fies.
The liquification of air is slow.
uncertain and expensive process. By
the most approved methods now known
it can be made only in verv small
qualtiti IS. The apparatus must be
constructed of such materials as are
not affected by this curious fluid. All
metals outside of gold, silver, copper
and platinum are changed by contact
with liquid air. A pressure of from
$500 to 5000 pounds to the square inch
is necessary to produce liquefaction.
This makes it's manufacture more or
less dangerous. Professor Patty told
of a plant on which $l5. 900 had been
spent. On the initial trial of the ap-
paratus, everything went we'll until
they applied the pressure of 900
pounds Then the whole machine
lost its identity. A nice sum of
money was gone and there was no
liquid air.
Professor Patty stated, however.
that he believed it would not be long
before far better, easier and cheaper

when amputating limb The part
to be cut is frozen with the liquid
air. This makes the operation pain

air cold il in many respects very diff

deaden the thing frozen except for the
, time being. The effect of the liquid
air disappears as soon as the object is
held in the atmosphere again.
The experiments performed were
startling and amusing. Fancy ket

looks like water. boiling on block

also tin dipper. Wood. vegetables.
beef steak all become as brittle as pop
corn when treated by it. Mercury
hardens until it can be used as ham
mer. Steel pens are welded together
by the magic fluid. The professor
passed the various things treated
throughout the audience for the close
inspection of everybody. The liquid
air entertainment was indeed most
enjoyable and instructive.
