                        Liquid Air as a Substitute for Gunpowder, Dynamite, Etc. - 
                    What is its Effect on Metals for Hardness and Electrical Conductivity?

Much interest is being manifested in the liquid air plant at the university. What benefit will it be? Of what use will it be put to outside of a mere startling discovery?

Dr. Freer anticipates that it will prove a most valuable acquisition to the university in the chemical department. There are some chemical reactions which can only be obtained by a very low degree of coldness. Said Dr. Freer: "Taking the liquid air as a motive power, I think its value is greatly over-estimated. I do not anticipate that it will be a substitute for steam or electricity, but still we cannot tell about what these things may develop into. What we will utilize it for in the chemical department is to produce reactions that can only be obtained at a very low temperature, and I think we may possibly discover some important facts. "

"What do you think of liquid air as a motive power?" was asked of Prof Cooley of the mechanical engineering department. Said he: "It would certainly be a great thing if we could get a vessel to contain it. For instance, it would be very convenient for automobiles. But you must appreciate the fact that in order to get liquid air you must first reduce it to 1-200 of its volume and then subject it to a very low degree of temperature which really equals much more compression.
I would like to see the kind of stuff a vessel could be made of that would contain liquid air so that none of its volitization would escape except at valves. Why, if you dip some absorbant cotton into liquid air and touch a match to it, it will puff up into an instantaneous flame. The explosion comes from a fine separation of the particles of liquid air, and the lighted match makes it expand quickly - instantaneously. lts explosive power is simply enormous. "

"Then what's the matter with making it a substitute for gun powder, dynamite, etc?" he was asked.

"There! Now you are getting at what I think will prove its great value.
Just as soon as Dr. Freer gets his machine running in good shape we will have some of the liquid air over in our department and will be experimenting with it as to its explosive powers."

"Are there any other lines along which you will conduct experiments with the liquid air?"

"Certainly," said he. "Immerse any metal in as low a temperature as liquid air produces, and there are, no doubt, some changes produced. What are they? I don't know, but we are going to have all the metals for tests. If the molecular arrangements are changed, perhaps some give a greater degree of hardness than we ever knew before. Then again, perhaps some of them will be increased in electrical conductivity. Suppose, for instance, copper could be made more valuable as a wire to convey electricity after being immersed in liquid air. It would mean thousands and thousands of dollars to companies. We will experiment along this line, and possibly we may be able to give out some most valuable information. "
