THE BULLET OR THE HOLE?

Which Gets Through the Board First3
Answers to Odd Questions.
When bullet is shot entirely
through q board. which gets through
1irst-the bullet or the hole the bullet
makes: The hole and the extreme
point of the bullet get through the
board at the same time. but the bullet
does not get entirely through the board
until after the hole is entirely through.
1t is evident that the rear of the bullet
must he out Of the hole it makes be-
Tore it is entirely through the board,
While the hole is entirely through just
az soon as the widest part of the bullet
haS passed through.
How cold is it when it is twice as
cold as degrees above zero? There
are two ZcroS, one marked o on the
thermometer. and one known as abso-
lutte zero. which is understood to mark
the absence of all heat. The zero of
Fahreuheit's thermometer is obtained
by immersing Il tube of mercury in a
mixture of snow and common salt
and marking tie place where the mer-
curry stands in the tube. Absolute zero
is 459 degrees below this zero. Now,
twice as cold is exactly equivalent
to half as hot; therefore, when it is half
as hot as = degrees above zero, or 461
f., it is 1905 degrees below the zero on
the thermometer
Is any man strong enough to break
an egg held. end to end between the
palms of his hands? The force required
to break an egg IN this manner has
been found to be between seventy-five
and eighty pounds. a great many men
can exert this pressure. The probable
reason for the failure of many to ac-
complish it is that they are a little
afraid of the result and do not press so
hard as they can.
If there was n tunnel through the
center of the earth and an iron ball
was dropped into it, where would the
ball come to rest? Unless it was re-
tarded by the resistance of the air, the
ball would go through to the other side
and then fall back to its starting point,
repeating this operation forever. If re-
tarded by the resistance of the air, it
would ultimately come to rest at the
center OF the earth.
When an automobile turns a sharp
corner at Il rapid rate of speed, which
pair OF wheels, inside or outside,
leaves the ground? The centrifugal
force developed by the automobile is
directed outward; therefore it is i'm
possible for it to tip inward. The out
side rail of a railroad track on curve
is made higher than the inside rail be-
cause of the tendency of the train to
tip outward. y practical demonstra-
ton may be had by standing on the
rear platform of 4 street ear and
noting which way the body is thrown
when the ear turns Il curve.
A chicken does not eat anything dur
ing the first twenty-fOur hours of it's
existence, yet it doubles in size What
does it live on? The amount of the egg
left In the chickens stomach after it is
hatched will supply nutriment for sew
cral days. As to the apparent increase
in size. when the organs are relieved
from the compression Of the eggshell
they expand; therefore the chick APP
pears larger. The down becomes fluffy
when dry, and this also increases the
size Of the chicken, but it is not a fact
that there is any great change in the
weight during the first day.
