** To Photograph a Man in a Bottle [74]
Neither a huge bottle nor a dwarfed man is necessary for this
process, as it is merely a trick of photography, and a very
amusing trick, at that.
First, photograph the person to be enclosed in the bottle against
a dark plain background and mark the exact position on the ground
glass. Let the exposure be just long enough to show the figure
distinctly. Then place an empty bottle against a dark background
and focus so as to have the outlines of the bottle enclose those
of the man. Let this exposure be about twice the length of the
first, and the desired result is obtained.
** A Musical Windmill [74]
Make two wheels out of tin. They may be of any size, but wheel A
must be larger than wheel B. On wheel A fasten two pieces of wood,
C, to cross in the center, and place a bell on the four ends, as
shown. The smaller wheel, B, must be separated from the other with
a round piece of wood or an old spool.
