Wonderful Effects May Be Produced
by the Aid Of Chemicals.
The Chinese Emperor Tai Tsung pos
sessed among other treasures picture
known as a magic painting. 1t repre-
sented a pastoral scene with COW
standing In a field and mountains be-
yond. When the picture was shown to
strangers or guests and they admired
II, the emperor would say:
Eyes, this Is remarkable painting
The cow, as you see, Is standing, but
II the room was darkened the cow
would think II night and would lie
down"
Then the emperor would order the
room TO be darkened, and the COW
would be seen TO be lying down, ap-
farently asleep.
The picture was a water color, over
which was painted I'm colorless phos-
phorescent paint similar picture rep
resenting the cow lying down. In the
liQht the standing animal was seen,
but Mt night or In n darkened room
only the phosphorescent picture was
visible. SO the magic picture was, aft
er all, a very simple trick.
A Dresden chemist named Schade
discovered method OF initiating 1t
which can be accomplished rs follows;
First paint In ordinary colors the
picture OF the cow standing. Then
melt some Zanzibar copal over a char
coal fire and dissolve fifteen parts OF II
In sixty parts of French oil of turpen-
tine. Filter this and mix with twenty
five parts OF pure linseed oil which has
been previously heated and cooled
Now take forty parts Of the varnish
30 obtained and mix with six parts OF
prepared calcium carbonate, twelve
parts OF prepared white zinc sulphdc
and thirty-six parts of luminous cal
cium sulphide, all OF which can be oh.
tained from any chemist.
This emulsion should be ground
very fine In a color mill. The result
Will be white luminous paint, which
should be used to paint the COW lying
down.
Many seemingly wonderful tricks
can be performed with the use OF
few simple chemicals. One of them Is
the ball OF fire. Take for this barium
sulphate (CP) one part, magnesium
carbonate (CP) one part, gum traga-
cunth q. =. This should be mixed and
rolled into marbles and kept at red
heat for about an hour, then allowed
to cool slowly and placed In a glass
stoppered bottle. A few hours before
using place In the sun, and the marbles
at once become luminous.
At the entertainment ordinary mar
bles are passed among the audience,
one or more Of the luminous marbles
being concealed I'm the hand. The ex
hibitor then takes a marble from some
one In the audience, holds II between
his thumb and forednger, blows upon
II and asks TO have the lights turned
down. AS this Is done he substitutes
the luminous marble, and the mysteri.
Gus light is seen. This is handed
around and changes again as the light
is turned on, when the magician pre-
sents TO the audience several of the
ordinary marbles as souvenirs.
Another trick is very effective. Take
two similar punches OF artificial flow.
ers. Brush one over with glue or mu-
cilage and powder II with the dust
from one Of the marbles described.
Then place In the sun. When taken
into a darkened room, luminous flow.
ers are seen. The magician exhibits
the flowers that have not been prepar.
ed and shows that there Is nothing pc
cullar about them. Then as the light
Is turned down he substitutes the CON
cealed bunch, blows upon the flow
ers and, presto, displays to the as
tonlshed observers luminous bunch,
ench flower of which stands out rs IL
at white heat.
Luminous letters can be written anG
exhibited in the dark to the wonder Of
the audience. Luminous ink is made
by placing n piece Of phosphorus about
the size OF n pea In test tube with n
little olive oil. Place the tube In n
water bath until the oil becomes heat
ed and the phosphorus liquid. Shake
well and pour into bottle with n
glass stopper. Admit air just previous
TO using 1t, and the fluid will become
luminous tracery In the dark.
Water can be rendered luminous In
very simple manner. Dissolve n
small piece of phosphorus In ether for
several days In glass stoppered bot
tie. In this place lump of sugar,
then drop the sugar I'm water, which
will at once become luminous.
Luminous paints can be made any
color-green, yellow. violet or blue
and II applied TO various objects make
a wonderful display at night
