in diameter and form the remaining portion of the wire into a
spiral, soldering the end in the bottom of the box near the cup.
Wrap the ring at the top of the spiral piece of wire all the way

around with the strip of asbestos paper, wrapping them together
over and over until the entire ring is covered. Slip the end of
the rubber tube over the tin tube on the side of the box and the
flash lamp is complete.
To make a flash with this lamp fill the little cup in the center
with flash powder and moisten the asbestos ring with alcohol. When
all is ready for the picture the alcohol is lighted and a quick
blow of the breath through the rubber tube will force the flash
powder upward into the flame and cause the flash.
When through with the lamp place the cover over it, pushing the
asbestos ring down inside the box. Wind the rubber tubing around
the box and you have a neat outfit that can be carried in the
pocket.
** Photographing the New Moon [174]
To make a photograph of the moon is quite difficult and no good
picture can be made without an expensive apparatus. At home and
with your own hand camera you can make a good picture of the new
moon by the use of a flash light on a tennis ball, the tennis ball
taking the part of the moon. The ball is suspended in front of a
black cloth screen, the camera focused by holding a burning match
near the ball and the exposure made by burning a

small quantity of flash powder at one side and a little below the
ball. The light from the flash only striking one side of the ball
gives the effect of the new moon. --Photo by M. M. Hunting,

** Removing Scissors from a Cord [175]
A piece of strong cord is doubled and fastened to a pair of
scissors with a slip knot, as shown in Fig. 1. After passing the
ends of the cord through the thumb hole of the scissors they are
tied fast to a chair, door knob or any other object that may be of
sufficient size to make the ends secure. The trick is to release
the scissors without cutting the cord.
Take hold of the loop end of the cord in the lower handle and
drawing it first
