The Truth About this Remarkable Discovery, as Understood by Prominent Scientists — A Presentation so Clear as to be Readily Understood by All. RADIUM, OF 300,000 INTENSITY (extremely powerful), is guaranteed — TO   BE   SHOWN   AND    USED    FOR    EXPERIMENTS.
The greatest sensation ever known in scientific circles has been created by Mme. and M. Curie's discovery of RADIUM, whose entirely new and remarkable properties have, to an unparalleled degree, attracted the attention of the reading world. This is partly because RADIUM has been an enigma to scientists, upsetting some long-established theories, while reconciling others; partly that the continued investigations are resulting in further discoveries, and that most remarkable predictions are made for its future. A demonstration of the unique qualities of RADIUM makes a fascinating and instructive voyage to the wonderland of science.
RADIUM   is    worth   several thousand   times  its   weight   in
pure gold; at  the  rate  of over $1,000,000  per  pound, the demand for it is much greater than the supply.
RADIUM, it is estimated, can continue to give out energy unimpaired for millions of years—a dynamo without the expenditure of fuel.
RADIUM causes genuine diamonds to burst into a phosphorescence when brought near, even when separated by metals, books, or other things ordinarily impenetrable.
RADIUM, immersed in Liquid Air (3120 below zero), continues to give out heat and light — apparently uninfluenced by its frigid surroundings.

RADIUM emanations are beautifully demonstrated by suspending a particle near a sulphide of zinc screen, lenses revealing a shower of flashing meteors, as the myriad rays or atoms bombard the screen. This mimic pyrotechnic display, it is estimated, will continue unceasingly for millions of years.
To secure the precious RADIUM grains may be likened to a search for specks of dust hidden in a sand pile, or I for drops of perfume scattered in a river. Tons and tons of pitch blende, the residue of uranium mines, are worked over for months and months, with infinite pains, aided by all the resources of chemistry—by boiling and filtering, decanting and ' crystallizing, with much fuming of acids and steady glow of furnaces— until a few grains of RADIUM salt are secured, of such concentrated strength as to possess many, many thousand times the radio-activity of metallic uranium.
RADIUM is a seemingly inexhaustible battery of energy, ceaselessly giving forth heat and light, without perceptible waste or diminution to itself. RADIUM constantly gives off three new and distinct kinds of rays, each possessing remarkable qualities—in
____________________addition to which are the
peculiar emanations of the RADIUM itself.
RADIUM has properties fatal to animal and seed life, when in proximity. It has to be handled most carefully, a coating of lead giving protection to the operator's hands.
Other properties of RADIUM give promise of incalculable benefit to humanity by therapeutical use, reliable European physicians reporting supposed cures from its use in the treatment of lupus, cancer and other diseases. Some predict its successful use for consumption, diphtheria, etc.
RADIUM rays will almost instantaneously penetrate rubber, metals, wood, and other opaque substances. No previously known e1ement, not even light or electricity, possesses such wonderful penetrative power.

BELOW ARE SOME OF THE EXPERIMENTS
To be performed by a skillful demonstrator, equipped with complete apparatus, a competent lecturer, thoroughly familiar with the subject, explaining the phenomena in the simplest of language. A supply of Liquid Air is positively guaranteed and all tickets are sold with this understanding. Perfected methods ensure safe transportation and retaining of liquefied air for from 10 to 20 days.
LIQUID AIR BOILS ON ICE
A kettle of Liquid Air boils on a cake of ice, "steam'' issuing freely from the spout. Boiling is further accelerated by putting a few pieces of ice in the kettle. Liquid Air, poured directly upon ice, quickly passes off in vapor, like water poured upon a red hot stove.
A LIQUID, YET ENTIRELY DRY
One's hand may be thrust into the Liquid Air and no moisture adhere. A handkerchief dipped for a few seconds is removed intensely cold, but absolutely dry. Blazing paper or wood, or a lighted candle, having Liquid Air poured upon them, are not extinguished but burn with dazzling brilliancy.
STRAWBERRIES FREEZE WHILE STEEL    MELTS
In the same small glass, and at the same time, Liquid Air melts steel pens with brilliant scintillations, and freezes strawberries or cranberries to 312° below zero.
An icicle is made of alcohol; whiskey and other substances ordinarily difficult to congeal, are easily frozen.
ITS   EXPANSIVE,NESS
is shown by blowing a whistle, filling a balloon, or forcing from a strong tube a plug which has been driven in with great force.
HUMOROUS EXPERIMENTS ARE     GIVEN
with steaks, eggs, fruits, handkerchiefs and other substances treated with Liquid Air.
Iron, tin and copper are made brittle and readily crushed.
A kettle containing Liquid Air is placed over a fire, and ice is formed in the kettle while in contact with the flame.
A     SPECTACULAR
experiment with flowers which are rendered exceedingly brittle but still retain their beauty and fragrance.
NAILS ARE DRIVEN WITH A HAMMER OF FROZEN QUICKSILVER
Illustration of Liquid Air as an explosive. Methods of applying Liquid Air for therapeu¬tical and surgical purposes are shown. Hair felt, wool, cotton, etc., are burned with a dazzling brilliancy, so completely that no odor arises and scarcely any ashes remain.
A geyser of snowy vapor is made to spout many feet in air. The wonderful Dewar Bulb is shown—the vacuum jacketed vessel in which Liquid Air is carried ; glass less than one-sixteenth inch thick, so strong as to with¬stand over a ton of atmospheric pressure
"WHERE EXTREMES MEET" —A MARVELOUS CONTRAST IN TEMPERATURES
HEAT 3500 ° ABOVE ZERO in contact with COLD 312° BELOW ZERO
Burning with brilliancy of an electric light carbon, in a tumbler formed of ice, containing Liquid Air. The latter consumes the carbon, and at same time prevents the intense heat from melting ice receptacle.   A rubber ball is immersed, and being thrown to the floor, breaks into scores of fragments.
