Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
519
These
two
covers
are
beforehand
prepared
for
the
trick
by
filling
the
two
compartments
of
each,
one
with
wine,
and
the
other
with
water.
The
air-holes
are
stopped
with
pellets
of
wax,
but
for
the
sake
of
distinction
the
“wine”
compartment
of
each
is
plugged
with
red
wax,
and
the
“water”
compartment
with
white
wax.
Any
other
distinguishing
mark
is,
of
course,
equally
good.
So
long
as
the
air-holes
are
thus
stopped,
there
is
no
fear
of
the
liquid
running
out.
The
performer,
having
filled
the
glasses
as
already
described,
mixes
the
contents
in
the
decanter,
and
in
placing
the
latter
on
the
stand,
removes
the
wax
plug
from
the
bottom,
thus
allowing
the
wine
to
run
out,
and
to
percolate
through
the
above-mentioned
holes
into
the
stand,
where
it
remains.
He
next
places
the
empty
glasses
on
their
respective
stands,
and
places
the
covers
over
them.
He
then
asks
the
audience
into
which
of
the
glasses
they
desire
that
the
wine
shall
travel,
and
into
which
the
water.
When
they
have
made
their
decision,
he
has
only
to
remove
the
red
pellet
from
the
cover
which
is
over
the
glass
into
which
the
wine
is
to
pass,
and
the
white
pellet
from
the
opposite
cover.
The
tying
of
the
tape
from
cover
to
cover
is
merely
designed
to
give
time
for
the
liquids
to
reach
their
respective
destinations,
and
is,
indeed,
altogether
dispensed
with
by
many
performers.
The
air-holes
may
be
stopped
by
means
of
tinfoil
pasted
over
them,
instead
of
the
wax,
if
preferred.
The
foil
is
instantly
removeable
by
scraping
with
the
nail.
