seen rising from the zinc. Wher
the action has continued long
enough to drive the air out, the ga'
escaping from the outlet may b'
ignited. 1t burns with blue flame
If mixed with air il is very explo
sive, otherwise it burns quietly
Collect several jars full over watel
(by the method to be explained I'm
der oxygen). Fill II small balloon
with the gas. 1t will rise rapidly
Connect the outlet tube with thu
stem of a clay pipe and make som'
soap bubbles filled with the gas. 4
little glycerine in the water i'm
proves the bubbles. They will ris'
rapidly in the air. If you can catcl
them with candle flame they vii
burn. If you can get or make
large bottomlcss jar with tube il
it's lid, fill il thrce-fourths full ot
air, or still better, one-third full OF
oxygen. Then fill the rest with ny
drogen and attach your pipe to the
tube. BY pressing the jar down in
to water any desired pressure may
be obtained. The bubbles will now
explode when ignited, and if oxygen
instead of air is used, the explosion
will be very loud. Take dish OF
soapsuds and blow this mixture i'll
to it until you have tall heap OF
bubbles. Set fire to il and there
will be tremendous explosion
which, however, will do no harm
even to the dish. Burn jet of n.y.
drogen inside the mouth of the i'll
verted jar. The resulting vapor will
condcnsc on the sides of the jar aud
run down. \ few drops can be col
lected and will be found to be water.
The oxygen came from the air. y
mixture of oxygen and hydrogen
is an invisible explosive gas. When
il is exploded or burned the result
is steam. which can be condensed
into water. 1t has ceased To he a
mixture and become chemical
compound.
Oxppcn can be made in various
ways. The best way is TO heat IA
mixture of potassium chlorate and
black oxide of manganese. 1t the
oxide cannot be pro-
cured. the potassium chlorate alone
will do, but il requires higher
heat. Mix together about equal
weights of potassium chloratc and
dioxide and put them
into flask or bottle with perfor-
atcd cork in which is a close fitting
tube; heat the bottle and the oXy-
gen will be given off. Fill a glass
Jar with water, invert il in "A bucket
o. tub of water, and raise it until
only the mouth is under water. The
water in the jar will not run out.
lWhy0 Pass n tube from your flask
into the mouth of the jar. Bubbles
of oxygen will displace the water
and finally fill the jar. Collect
several jars full. If you have
to use the potassium chloratc
alone il may be well to make met
nj retort. as the heat necessary
would break an ordinary bottle. y
small tin can with criLnped joints
and a screw lid can be made into "a
very good retort by sealing the
Joints on the inside with plaster of
Paris. A jeweler can easily drill
The head out ola revolver cartridge
and fasten il into the lid. a glass
tube can then be sealed into this
with plaster of Paris. 1t may be
necessary to seal the lid on with
plaster after putting in the chloratc
and to do the work all over each
lime the apparatus is used.
Hydrogen is much lighter than
air, and an open jar of it should be
carried with the mouth downward.
Oxygen is slightly heavier than air
and the jar should be carried with
the mouth upward and the hand or
4 piece of paper over it.
Bend n spoon so the bowl is per-
pendicular TO the handle. Pass the
handle through slit in a chalk
box cover. Put n small piece of
into the spoon and
light one corner of il. 1t will burn
slowly in the air. Put it into oxy-
zen and il will burn brilliantly.
Get a broken watch spring from
1 jeweler. Straighten il and pass
I through a slit in the chalk-box
,over. Wrap thread around the
over end and dip it in melted
sulphur. Light the sulphur. Put
he watch spring into jar of oxy-
zen. 1t will catch fire and burn
brightly. All these experiments
ire very brilliant in dark room
Burn zinc, copper, and other metals
n the same way.
Hydrogen will burn, but nothing
will burn in it. Oxygen will not
,urn, but substances which burn in
Iir will burn more brilliantly in OK
gen, and some substances, as iron,
which burn with difficulty in air,
urn easily in oxygen. Air is di-
uted oxygen. What is ii diluted
With?
THIRD.-Air is a mixture of oxy-
zen and nitrogen. 1t is not easy to
rove absolutely that air is a mix
