To Make Liquid Air

To Make Liquid Air

The University of Michigan To Do It.

A Present From Brush

The Greatest Recent Discovery in Science.

Air Made Into a Liquid that Boils on Ice, Freezes Pure Alcohol, and Burns Steel Like Tissue Paper and Can Be Poured Like Water.

The university has been presented with an apparatus for manufacturing liquid air by Charles S. Brush, the geart electrician of Cleveland, Ohio. The present was announce to the board of regents which was in session at the university Wednesday by Prof. Paul C. Freer. The apparatus cost $1,200 and has already been contracted for be furnished the university on October first and only awaited the acceptance of the university. Very naturally the regents accepted the gift. It will be placed in the basement of the chemical laboratory.

By this apparatus it is said that air can be reduced to a clear sparkling liquid, that boils on ice, freezes pure alcohol and burns steel like tissue paper and yet it can be dipped up in an old sauce pan and poured about like water. It is not wet to the touch, however, and burns like a white-hot iron and when exposed to the open air for a few minutes it vanishes in a cold gray vapor, leaving only a little white frost.

With this machine, it is said, two parts of liquid air will make ten parts, which in turn can be used to make more, and so on. Air liquifies at 312 degrees below zero, so that some idea of the intense cold can be obtained. When liquid air is exposed to the heat of the atmosphere, usually about 382 degrees warmer it expands and in this way power in the machine is produced.

The discover is one which bids fair to revolutionize the methods of producing power and all investigations in this comparatively new domain of science will be of interest and it is well that the university is to be equipped with an apparatus of the kind through the generosity of Mr. Brush.
