Then add. from time to time. a few small
pieces of phosphorus. \ multitude of gas
bubbles will be produced, which Will fire
on the surface of the effervescing liquid.
The whole surface of the liquid will be-
come luminous and fireballs. with jets of
flame, viii dart from the bottom through
the fluid. with great rapidity and a hiss
ing noise.
FIRE AND WATER.
To illuminate the surface of water wet
a lump. of fine loaf sugar with phosphor-
lied ether and throw ii into a basin of
water The surface of the water will be-
come luminous in the dark and, by gent
ly blowing upon 1t. phosphorescent I'M
dulations will be formed. which illuminate
the air above the fluid to a considerable
distance.
To set combustible body on fire, by
the contact of water fill a saucer with
N-ter and let fall into 1t a piece of po-
/ tasstum of the size of a pepnercorn; the
potassium will instantly burst into flame
with slight explosion, and burn vividly
/ on the surface of the water, darling at
I the same time from one side of the vessel
! to the other, with great violence, in the
! form of beautiful redhot fireball.
For the experiment called animated fire,
put some small pieces of camohor in
basin of pure water; very peculiar mo-
ton commences : at once. some of the
pieces turn as If on an axis, others go
steadily around the vessel, some seem 10
be pursuing others. and thus they con-
tinue forming a curious and pleasing APP
pearance. But if a single drop of sui
phuric acid be put into the water the
motion of the camphor stops instantly.
If d piece of camphor is lighted and then
carefully placed on the water. ii burns
with a bright flame: moving about with
great rapidity. as If in search o. some
thing. but is instantly stopped by drop
of sulDhuric acid.
COLORED FIRES.
To make livid green colored fire I'M
der water, put into a large tumbler two
ounces of water. and add first piece
of PHOSPHORUS about as big as pea,
and then 50 grains of chloride of potash.
Then, by means of a funnel, with long
neck, reaching to the bottom of the
glass, add six drains OF sulphuric acid.
AS soon the acid comes in contact
with the other materials flashes of fire
begin to dart from under the surface OF
the fluid When this takes place drop
into the mixture few Jumps mot pow
der) of OhoSnhuret of lime of the size
of pea. This will instantly illuminate
the bottom or the vessel, and causes
stream OF fire, emerald green in color. to
pass through the fluid. By a fresh adj
dition of the same materials the action
may be kept up when it begins TO sub
side.
10 change a blue liquid to a red. pour
a little of the infusion of litmus into
wineglass, and add to it single drop
of nitric or sulDhuric acid. and Il will |
be changed instantly to a beautiful red
color.
To change red or blue liquid to green, |
take q little Ol the InenliOntQ
the above experiment either before or
after 1t has been converted to red and |
add few drops of the solution of soda, |
and. upon stirring IL, fine green color /
will be produced.
TO make the same liquid assume va /
rious colors. mi- some powdered man |
ganese with a little inter- and throw the |
mixture into red hot crucible. and |
compound will be obtained possessed of |
the singular property of different colors, |
according 10 the quantity of water that is !
I'D cd RI 4 small utt 0ivaS n
green solution: q greater quantity !
changes it to blue; more still, to Dur-
pie and a still larger quantity to a beau
tiful deep purple. The last experiment |
may be varied by putting equal quantities
of this substance into separate glasses. |
and pouring hot water on the one and /
a portion of cold water on the other;
the hot solution will be green and the
cold one deep purple.
