How to make easily black foam using chemical magic

Action:

TWO 200 ml. beakers are standing on the table. you pick BLACK CARBON them up, pour a clear liquid from one beaker into the other, which is one-tllirtf full of a white powder. Stir well with a stirring rod for a Fcw seconds aid then place the beaker on the table. Placing a white cal.dl)oat.d 1)ehind the beaker, the material begins to darkcn and  gives off fumes. In a few minutes a Black solid will rise several itlches above the beaker

You Need:

About 10ml. of conc sulfuric acid in the first beaker; 

powdered sugar in the second;

stirring rod.

Why:-

Black carbon remains wtren the sulfuric acid removcs the elements hydrogen and oxygen from sugar.cause the niaterial. to rise or Joarn.

Suggestion

For an instantaneous reaction, try the following experiment. From two 200 ml. beakers, pour two liquids simultaneously into an enipty 4800 ml. beaker. One contains 50 ml.concentrated sulfuric acid; the other is a concentrated sugar solution made by d i s s o l v i i~1~3 0 g r a n~so f sugar in 1~0 0m l.of water. Immediate reaction with considerable frothing occurs when the liquids come in contact. A large plate 01 paper should be under the beaker to catch the overflow the first metod produces sulfur dioxide fumes that are somewhat suffocating in a small ro0.m. The formalion of Black powder  gives the Demonstration a special appeal.

Magic to make Burning fire under Water

A MIXTURE of nitrate of potash, powdered charcoal, sulphur, and strontium nitrate driven into a strong paper case about two inches long, well closed at the end and varnished so as to be quite waterproof,may be set on fire and will continue to burn under water until the whole is consumed, provided that the cartridge be burnt mouth downwards (Fig.). The best effect is produced when burnt in a deep glass jar. 

Requirment:-

The combustible (red fire) is  made by mixing by weight:

strontium nitrate 40 parts,

flower of sulphur 13 parts,

chlorate of  potash 5 parts,

sulphuret of antl mony 4 parts.

Powder the ingredients separately, and then mix carefully on a sheet of paper with a paper knife. On no account must sulphur and chlorate of potash be rubbed together in a morta . being very liable to explode. The composition should not be kept for any length of time  before using, as is liable to spontaneous combustion.

magic of fluroscent writting...............

If a design be written or drawn on white paper, using a solution of sulphate of quinine as the ink, such design or writing when dry will be quite invisible. But if it be exposed in a dark room to the light of an ordinary Geissler tube or similar electric light the writing or design will appear in blue.

Similarly, if tungstate of calcium were used on a" brownish TIG. 8. or darkish paper, and the design exposed to the action of the X Rays (the X Ray bulb could itself be wrapped in black paper or placed in a cardboard or even a wooden box), it would appear in phosphorescent white.

If the (much dearer) chemical, barium platinocyanide be used, tne phosphorescence is much stronger and of a greenish tinge. It is with this chemical that X Ray
screens are. coated. Another chemical almost equally brilliant (phosphorescing blue) is potassium platinocyanide; it is also equally dear.

A magic of colour devoloper..........

Apparatus:-

A wooden frame (such as a slate or picture frame) on which is tightly stretched a piece of " unbleached " muslin. 

Chemicals:-

Sulphate of iron, nitrate of bismuth, sulphate of copper, prussiate of potash. Dissolve a small quantity of each of the chemicals in warm water. The first three named are your painting solutions, the last your " developer," as it were. Using a separate brush for each colour, paint 0K1 the muslin some (outlined) picture or design. It is not advisable to attempt much detail. Allow each colour to dry before painting the next. 

When dry all are quite invisible:-

To develop or bring out the picture all that is necessary is to spray on to the muslin a solution of prussiate of potash; the effect is hastened if the muslin is very slightly damp. When sprayed on with this chemical the sulphate of iron comes up blue, the nitrate of bismuth yellow, and the sulphate of copper brown. If the prepared frame be hung in such a manner that the developer can be sprayed on from behind without the knowledge of the audience the effect in a magical sense is much heightened. An ordinary scent spray or atomizer can be used, the sound being hidden by a little music.

To turn Water to Milk and back again......very simple method

White fluids representing milk, etc., may be formed by
mixing soluble salts (in solution) with suitable agents, so
that the final result shall give a white precipitate in
suspension ; but the results differ much in appearance
and only a few salts are suitable. Soluble calcium salts,
as calcium chloride, are rendered insoluble, forming white
deposits with sulphates or carbonates, as sodium carbonate
or sodium sulphate. Soluble silver salts act in the same
way with chlorides, such as sodium chloride; as do also
the soluble salts of lead. Mercury salts and ammonia
give like results, and magnesium hydrate and sodium or
potassium hydroxide give heavv curdy precipitates
take one or two of the best:—
(1) To form a fluid resembling milk, mix strong
solutions of calcium carbonate and sodium carbonate;
to clear it, use hydrochloric acid.
(2) Use nitrate of silver and a saturated solution of
pure chloride of sodium; this is cleared by ammonia.
Avoid shaking, or the milk goes into curds at once.
The chloride of sodium must be pure—common salt is no
good.
(3) Sulphurous acid and acetate of lead, which is
cleared by strong nitric acid.

change IQUID COLOUR EFFECTS...Water to Ink, Ink to Port, Port to Water

Apparatus.—A decanter of about a pint capacity filled
(as before) with distilled water; seven wine-glasses alike
in shape.
Chemicals.—Tannin, perchloride of iron, oxalic acid.
About as much tannin as will lie on a sixpence is
dissolved in the distilled water in the decanter. Of
the glasses, numbers one and three are unprepared;
numbers two and four contain two drops of perchloride
of iron; number five about ten drops of a saturated
solution of oxalic acid ; number six the same quantity
liquid ammonia; and number seven a small tea-spoonful
of sulphuric acid. On pouring from the decanter, the
first glass (unprepared) gives clear water, the
gives ink, the tliird clear water, the fourth ink once
more (Fig. 1). The* contents of all four glasses are then
returned to the ^ decanter—the whole then appearing
as ink. The first four glasses are then filled from the
decanter, the contents still appearing as ink. A wave of
the magic wand over the fifth glass changes the ink
when poured in from the decanter to clear water, and
a wave in the reverse direction changes the same fluid
to port, or more strictly speaking to claret, in the case
of the sixth glass. The contents of all six glasses are
then emptied back into the decanter, the whole being
claret coloured. Once more six glasses are filled with
claret coloured liquid ; another wave of the wand or
suitable action as the performer fills glass seven
produces clear water once more.
The effect is much heightened if the glasses are not
arranged in a row but apparently haphazard, and
the final and semi-final changes not seemingly made
in any particular glass.
On no account should the contents be tasted.
v This experiment is one of many that can be performed
with quite ordinary chemicals, such as iron (salts),
tannic and gallic acids, salicylates, and such like
chemicals. By dissolving a few drops of ferric chloride
or perchloride of iron in water, the result is a colourless
liquid; but on introducing a few drops of a tannate or
gallate, the liquid is at once darkened, ferric gallate or
tannic galla*te being formed. To restore the liquid to
its original colour a suitable reagent must evidently
be used. Any acid which forms a colourless soluble
salt when added to the tannate would answer the purpose.
Oxalic acid is nearly always used, being the leastCHEMISTRY AND CHEMICAL MAGIC .
corrosive, easy to handle, and portable in a crystalline
form.
If we use a salicylate, such as sodium salicylate, in
place of a tannate, a beautiful purple colour is the
which can be reacted upon or cleared as before.

convert Wine in to Water

Apparatus.—Two claret (or wine) glasses and two
perfectly transparent decanters, one containing red wine
the other water.
Chemicals.—Permanganate of potash, pure sulphuric
acid, hyposulphite of soda.
If one gramme of permanganate of potash and two
grammes of sulphuric acid be dissolved in a quart of
(distilled) water a red liquid resembling wine is produced.
This liquid can be instantaneously decolourized by
pouring it into a glass containing a few drops of a
concentrated solution of hyposulphite of soda. A little
pinch of aniline dye, mixed into a paste with glycerine,
and stuck to the bottom of a second glass—(this device
permits of the gljiss being inverted or accidentally upset
without the contents being lost)—is sufficient to change
water to the colour of wine.
Decanter No. 1 contains clear water, decanter No. 2 the
permanganate and acid solution. One glass is unprepared
and one prepared as stated with the dye. The actual
presentation of any experiment will in general be left
to the taste of the reader. The usual method of procedure
in such cases as the above is as follows. One
of the guests or audience is asked to join the performer
in some refreshment. The guest is asked to select
one of the two decanters, and he will generally take the
one (»ntaining wine. On his pouring the contents into
the tumbler containing the hyposulphite of soda, it instantly
becomes colourless, and the water in the other
decanter is apparently turned into red wine on being
poured inte the second glass prepared with the aniline
dye. The glasses etc. should be immediately removed
on the conclusion of the experiment, owing to the turbid
appearance that the red liquid will assume after a few
minutes.
The mixtures are poisonous and must not on any
account be drunk.

Red-Black (Divide) Location

Red-Black (Divide) Location
I don't think I have to tell you that now you can count the cards of a
borrowed deck, do the deal jog to separate the reds and blacks, and then do
any of the standard selected-card locations utilizing the color separation.
Basically, have a card selected from one half of the hand-to-hand spread and
replaced into the other half, and so forth.
But here's a way to do this with which I've "taken in" magicians for years.
The idea has been ripped off a few times through the years, so it must be
good.
Assume you're in position-the cards are color separated (via The Great
Divide, or any other way). Have a card freely selected from the top half,
remembered-keep spreading-and have it replaced about a quarter of the way up from bottom. Square. It's all very clean.
Then, table the deck to riffle-shuffle position, cutting the lower half deck
to the left. Move back a bit so that you can comfortably see the long sides
of the cards, and start to legitimately riffle shuffle the halves into each
other. Just look at the long sides (of the left half particularly) and the
odd-colored card will stand out like the proverbial sore thumb!
(Particularly if you lift the cards of the left half a bit more than usual
as you shuffle.)
You don't need to know which color was, or is, where. It will be either a
red card among (near center of) the blacks, or a black card among the reds.
Either way, it will be hard to miss.
The thing to do is to "catch" that odd-colored index as you riffle shuffle
without pausing, without hesitation. Try it; you'll see that it's
easy to do. Remember the card, of course. Complete the shuffle. Then do one more riffle shuffle.
You've "broken" the red-black stack-the cards are really mixed- and you know the selected card. Let the spectator shuffle, and end however you like.
Afterthoughts: If you handle it so that there's no suspicion of a red-black
separation, this must fool!
