THE BULLET Oh THE hole.
Which Gets Through the Board First -
answers to Odd Questions.

When a bullet is shot entirely
through board, which gets through
frst-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, bnt the bull
let does not get entirely through the
board until after the hole is entirely
through. 1t is evident that the rear
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 as soon as the widest
part of the bullet has passed through.
How cold is it when it is twice as
cold as 2 degrees above zero? There
are two zeros, one marked on the
thermometer and one lznnwn ~tse
lutte zero, which is understood to
mark the absence of all heat. The
zero of Fahrenheit's thermometer is
obtained by immersing tube of mer-
curry in mixture of snow and CON-
mon salt and marking the place where
the mercury stands in the tube. Abb
solute zero is 45o degrees below this
zero. Now, twice as cold" is ex-
actly equivalent to half as hot there
fore, when it is half as hot as de-
grees above zero, or 46I F., it is
23o.5 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 re-
quired to break an egg in this manner
has been found to be between seven
ty-fve and eighty pounds. A great
many men can exert this pressure.
The probable reason for the failure
of many to accomplish it is that they
are a little afraid of the result and do
not press so hard as they can.
If there was a 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 fail back to its
starting point, repeating this opera
ton forever. If retarded by the
resistance of air, it would ultimately
come to rest at the center of the
earth.
When an automobile turns sharp
corner at 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
outside rail of a railroad track on a
curve is made higher than the inside
rail because of the tendency of the
train to tip outward. A practical de-
monstration may be had by standing
on the rear platform of a street car
and noting which way the body is
thrown when the car turns curve.
A chicken does not eat anytA ling
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 stom-
ach after it is hatched will supply
nutriment for several days. AS to
the apparent increase in size, when
the organs are relieved from the COM
preston of the eggshell they expand,
therefore the chick appears larger.
The down becomes fluffy when dry,
and this also increases the size of the
chicken, but it is not fact that there
is any great change in the weight the
first day.
Why does an egg weigh more after
it has been boiled than before? The
increase in weight is due to the mois-
ture which has been absorbed by the
porous shell of the egg.-SNnday
