the solution into shallow dish, and dip
the slide into it. Raise it gently, and
film will be left in the hole. Slip the slide
with care into the lantern, and await re-
suits. For a moment, the circle OF light
on the wall remains clear, but soon, at
| the bottom, a faint tinge OF color APP
pears, growing stronger and stronger,
and moving upward. 1t settles into
| a band of color at last, still moving stead
| ily upward, and succeeded by another
| band of another tint, which follows it,,
and so on, until the great circle on the
wall is gorgeous with the same beautiful
hues as appear on the bubble, but not
| stirring uneasily together as these seem,
| but in regular bands ever moving up
ward. Now jar the slide gently, and
presto! the bands break and whirl to-
| gether in an astonishing maze OF color,
| wonderful in beauty. This Is really one
of the most beautiful experiments I'M
| aeinable, and will never fail to call
forth hearty admiration.
Now for an exceedingly amusing ex-
pertinent the harnessed soap-bubble.
| Take piece of the thiInest writing
paper YOU can find, and from it cut a
circular piece a little less than dime
in size. To one end of this attach p
| thread by the aid of a tiny drop OF seal
| ine-wax the less the better. Blow the
bubble to an ordinary size, and then
touch the round piece oit gently. The
bubble will adhere to 1t, and by gently
| tipping the pipe you may leave the bub-
BILE suspended by the string.
A bubble blown from the mouth sinks,
but if the pipe is attached by piece OF
| rubber tubing to gas fixture, the bub-
bic then blown being filled with gas
lighter than air will be carried upward
as far as the string will allow. Thus
YOU have veritable balloon, and if just
sufficient string is allowed to keep it
balanced midway between floor and
ceiling, it will perform very curious
| antics. Those currents of air which ex-
list in every room, unfelt by the inmates.
are strong draughts to the fragile and
delicate bubble. 1t will follow these
currents, now visiting the ceiling, now
running along the floor, and escaping
as if by miracle the obstacles in its
| path. If there is a lamp or gas jet in
the room it will be gradually attracted
toward it, and, carried by the upward
current of hot air, will dash toward the
ceiling, as if benton committing suicide.
But bounding on the cushion of dead
air, which always lies on the surface of
every solid object, it bends at right
angles, and darts off, escaping as If by
some inward power the fate into which
it was apparently plunging headlong.
and again circles round the room, till
drawn second time into the current Of
hot air.
| The ingenious reader will be able to
work up the hints above given into
variety of amusing and beautiful expert
ments. The last described will perhaps
afford most amusement in various
ways, which will readily occur to his
mind while using the novel toy. The
true secret of success in these expert
ments, as in everything, is carefulness.
If the soap solution is prepared with
care, there is no reason why the reader
should not be entirely successful in the
experiments that follow.
Bubbles are most curious and lovely
| things. There is neither time nor space
to go into their connection with science.
and the deep natural truths which they
are used to prove. The reader can at
least admire their gorgeous coloring
and airy grace, and find a moral in their
short but lovely lives.-Rer. G. G.
