1. Professor Frostbite was in Antartica gathering climate data which he
relayed to his home base by radio. One morning he reported the temperature as
minus forty degrees. The person receiving the data was a new operator and he
asked the professor if that was farenheit or celcius. The professor replied, I
don't care which scale you use, just be sure to get it down that it reached
minus 40.
Why would an eminent scientist be so careless about his data?
**********************************
2. There are two ships of equal size and strength. One is made of wood and
the other of steel. Can you tell which one is heavier and why?
**********************************
3. It takes Clinton three hours to paint a fence. It takes his little brother
Paul six hours to paint the same sized fence. Their mother wants them both to
paint the fence. How long should it take them if they both work at their
normal speed.
**********************************
4. NASA was considering sending canaries in space to study them under zero
gravity. They changed their minds when someone pointed out that no matter how
much water they provided for the canaries, the birds would quickly die of
dehydration. Why?
**********************************
5. John F. Kennedy was the youngest person elected to the presidency. How did
it come about that he was actually the second youngest man to hold this office?
**********************************
6. In Hawaii, if you drop a steel ball weighing five pounds from a height of
45 inches, will it fall more rapidly through water at 20 degrees Fahrenheit of
water at 40 degrees Fahrenheit. Or will it make no difference?
**********************************
7. A man and his son who are walking together, step out with their right feet
first. The boy walks three paces to cover the same distance that the man
covers in two. When will they both put their left feet forward together?
**********************************
8. Picture an empty wine bottle with a cork secured at the top in the usual
way. Inside the bottle a metal ring hangs suspended by a string. How is it
possible to make the ring drop to the bottom of the bottle without touching the
ring, the thread, the cork or the bottle.

1. Minus forty degrees is the only place where the two scales read the same
temperature. Minus 40 degrees celcius is exactly the same as minus 40
farenheit.
**********************************
2. The ship made of wood is heavier. Pound for pound, steel is heavier than
wood. If you want the wood ship to be as strong as the steel one, it will take
a lot more material.
**********************************
3. Two hours. Clinton can complete 1/3 of the fence in the first hour, while
Paul completes 1/6 of the fence. After two hours, Clinton has painted 2/3 of
the fence, and Paul has painted 2/6 or 1/3 of the fence. So the whole job is
completed in two hours.
**********************************
4. Most birds require gravity to swallow. Humans can swallow even while
hanging upside down. But canaries need to take a beakful of water and hold up
their heads, allowing gravity to take the water down their throats.

5. Theodore Roosevelt assumed the position because of a death. John F.
Kennedy was 43 when he was elected to the office. Vice-President Theodore
Roosevelt, however, was 42 years of age when he was sworn in as President after
the assassination of President McKinley.
**********************************
6. The ball will fall more rapidly through water at 40 degrees Fahrenheit. At
20 degrees Fahrenheit the water would be ice
**********************************
7. Never. Every second cycle, their right feet will go forward together, but
never their left.

8. By using a magnifying glass and the sun's rays you can burn through the
string and consequently cause the ring to drop to the bottom of the bottle.
