Here's another puzzle, not really a riddle.

A man is sitting in a row boat in the middle of a lake holding a bowling ball. He drops the ball into the lake. What effect and to what degree does this have on the water level in the lake, if any. Assume for the purposes of this discussion that the bowling ball has a density such that it's weight is equal to four times it's volume of lake water.

<font size="2" face="Verdana, Helvetica, sans-serif">Um... I think the level of the water will drop. The bowling ball will displace its volume, but it was already displacing four times its volume while it was being held by the guy in the boat.

A blonde was speeding in a 35 mile per hour zone when a local police cruiser pulled her over and the officer walked up to the car. The Female police officer also happened to be a blonde and she asked for the blonde's driver's license. The driver searched frantically in her purse for a while and finally said to the blonde policewoman, "What does a driver's license look like?" Irritated, the blonde cop said, "You dummy, it's got your picture on it!" The blonde driver frantically searched her purse again and found a small rectangular mirror down at the bottom. She held it up to her face and said, "Aha! This must be my driver's license" and handed it to the blonde policewoman. The blonde cop looked in the mirror, handed it back to the driver and said, "You're free to go. And, if I had known you were a police officer too, we could have avoided all this hassle."

Exercise of the brain is as important as exercise of the muscles. As we grow
older, it's important that we keep mentally alert. The saying; "If you don't
use it, you will lose it" also applies to the brain, so.......Below is a
very private way to gauge your loss or non-loss of intelligence. So take the
following test presented here and determine if you are losing it or are
still "with it." The spaces below are so you don't see the answers until you
have made your own....OK, relax, clear your mind and.... begin.

===========

1. What do you put in a toaster?







The answer is "bread." If you said "toast," then give up now and go do
something else. Try not to hurt yourself. If you said, "bread," go to:

Question 2. Say "silk" five times. Now spell "silk." What do cows drink?















Answer: Cows drink water. If you said "milk," please do not attempt the next
question. Your brain is obviously over stressed and may even overheat. It
may be that you need to content yourself with reading something more
appropriate such as "Children's World." If you said, "water" then proceed to
Question 3.

3. If a red house is made from red bricks and a blue house is made from
blue bricks and a pink house is made from pink bricks and a black house is
made from black bricks, what is a greenhouse made from?













Answer: Greenhouses are made from glass. If you said "green bricks," what
are you still doing here reading these questions?? If you said "glass", then
on to Question 4.

4. Twenty years ago, a plane is flying at 20,000 feet over Germany. If you
will recall, Germany at the time was politically divided into West Germany
and East Germany. Anyway, during the flight, TWO of the engines fail. The
pilot, realizing that the Last remaining engine is also failing, decides on
a crash landing procedure. Unfortunately the engine fails before he has
time and the plane crashes smack in the middle of "no man's land" between
East Germany and West Germany. Where would you bury the survivors? East
Germany or West Germany or in "no man's land?"















Answer: You don't, of course, bury survivors. If you said ANYTHING else, you
are a real dunce and you must NEVER try to rescue anyone from a plane
crash... Your efforts would not be appreciated. If you said, "Don't bury the
survivors" then proceed to the next question.

5. If the hour hand on a clock moves 1/60 of a degree every minute then how
many degrees will the hour hand move in one hour?















Answer: One degree. If you said "360 degrees" or anything other than "one
degree," you are to be congratulated on getting this far, but you are
obviously out of your league. Turn your pencil in and exit the room.
Everyone else proceed to the final question.

6. Without using a calculator -- You are driving a bus from London to
Milford Haven in Wales. In London, 17 people get on the bus. In Reading, six
people get off the bus and nine people get on. In Sweden, two people get off
and four get on. In Cardiff, 11 people get off and 16 people get on. In
Swansea, three people get off and five people get on. In Carmathen,
six people get off and three get on. You then arrive at Milford Haven. What
was the name of the bus driver?















Answer: Oh, for crying out loud! Don't you remember your own name? It was
YOU, dummy...the very first line says that you're driving the bus.

Now pass this along to all your "friends" and hope they do better than you
did.

<font size="2" face="Verdana, Helvetica, sans-serif">While in the boat, the bowling ball gets full displacement for its weight due to the nature of boats. Once in the lake, the bowling ball gets full displacement on its volume only. So, you have -4+1 = -3 bowling ball volume displacements (lake goes down).

So, the water level drops a number of inches such that the number of inches dropped * the surface area of the lake (after taking into account irregulariteis in the shape) is equal to three times the volume of the bowling ball. In other words, it will drop, but scarcely noticeably.

Also, the lake level may temporarily rise somewhat due to the splash and ensuing ripples.

Re: Jokes and Riddles Centre
 

seems to me it wouldn't change, except for ripple's.

Re: Jokes and Riddles Centre
 

Yep, it would drop 3 volumes.

Crypto? Isn't that just a cipher? Doesn't 'crypto' require that the substitution table change?

Impressive job there, man. And thanks for laying out exactly how you did it. That was especially cool.
