** How to Make an Atomizer [158]

Secure a good-sized test tube and fit it with a cork. Take two
glass tubes, with about 1/8-in. hole, and bend them as shown in
the sketch. This is done by heating them at the proper point over
a gas flame until they are soft. Two holes are bored through the
cork and the bent tubes inserted in them, as shown in the sketch,
so that one of the tubes will extend nearly to the bottom

of the test tube and the other just projecting through the cork.
The spray tube may be made with a fine hole by first securing a
tube longer than necessary and heating it at the proper point and
drawing the tube out into a fine thread. The thread is broken off
at the proper place to make a small hole.

** Home-Made Kits for the Camera [159]

If you have a 5- by 7-in. camera and wish to use some 4- by 5-in.
plates, make a few simple kits to hold the smaller plates and fit
the larger holders, says Camera Craft. Take two pieces of
pasteboard, A and B, black surfaced if possible, and exactly 5 by
7 in. in size. The piece A will form the back of the kit and
should have an opening cut in the center 4 by 5 in. in size. Paste
a piece of strong black paper, C, over the under side of it to
keep the plate from falling through. Cut an opening in the other
piece, B, but cut it 1/4 in. shorter. This opening, being 1/8 in.
shorter at each end, will retain the plate in position and cut off
only that small amount of plate surface when the plate is exposed
in the

long. Lay it down on a piece of newspaper and coat one side with
gum or mucilage. Stand the two pieces of 5 by 7 in. black cards on
end together so that they will be square and true and bind the
other ends with the strip of cloth so as to form a hinge. The two
cards form a thickness about equal to a thick glass plate, and go
in the holder in the same way. Lay one of these kits down against
the ground side of the focusing screen and draw a line around,
inside of the opening. This will be a guide as to just what will
be secured upon the smaller plate when the kits are used.

** How to Make a Miniature Stage [159]

A good smooth box, say 8 in. wide, 10 in. high and 12 in. long,
will serve the purpose for the main part of this small theater.
