Answers to Odd Questions

WHEN bullet is shot entirely through board,
w which gets through first-the bullet or the hole
the bullet makes? The hole and the extreme point
of the bullet get through the board at the time,
but the bullet does not get entirely through the
board until after the hole is entirely through. 1t
is evident that the of the bullet must be out
of the hole it makes before it is entirely through the
board, while the hole is entirely through just
soon as the widest part of the bullet has passed
through.
How cold is it when it is twice as cold as two
degrees above zero? There two zeros, marked
the thermometer, and one known absolute
which is understood to mark the absence of all
heat. The zero of Fahrenhet's thermometer is
obtained by imnersing tube of mercury in mix
ture of and common salt, and marking the place
where the mercury stands in the tube. Absolute
is $50 degrees below this zero. Now, twice
cold is exactly equivalent to half as hot, there
fore, when it is half as hot two degrees above
zero, 46I Fahrenheit, it is 23o.5 degrees below
the zero the thermometer.
Is any strong enough to break 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-fve 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 a little afraid of the
result, and do not press SO hard they
If there was tunnel through the center of the
earth and iron ball dropped into it, where
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 ult
mately come to rest at the center of the earth.
How an Auto Turns Corners
WHEN an automobile turns sharp corner at
w rapid rate of speed which pair of wheels inside
or outside, leaves the groundf The centrifugal
force developed by the automobile is directed
outward therefore, it is impossible for it to tip
inward. The outside rail of railroad track on a
curve, is made higher than the inside rail, because
of the tendency of the train to tip outward prac
teal demonstration may be had by standing on the
platform of street and noting which way
the body is thrown when the turns
A chicken does not eat anything during the first
twenty -four hours of its existence, yet it doubles in
size. What does it live on? The amount of the egg
left in the chickens stomach after it is Matched will
supply nutriment for several days As to the ap-
parent increase in size when the organs relieved
from the compression of the egg shell they expand
therefore, the chick appears larger The down be-
comes fluffy when dry, and this also increases the
size of the chicken but it not fact that there is
any great change in the weight during the first day
Why does egg weigh more after it has been
boiled than before? The increase in weight is due
to the moisture which has been absorbed by the
porous shell of the egg.
Why does water put out fire? Water reduces the
temperature of the flame below the point of igniton
therefore, it cannot burn. Water does not smother
the flames, when the burning brand is COM
petely immersed in a tank of water, because the
first contact puts out the fire; that is reduces the
