Ping-pong pipe puzzle
An empty steel pipe 5 centimeter long is embedded in a concrete floor. The pipe has an internal diameter of 40 millimeters. The concrete floor has a tiny drain hole which means the pipe in unable to hold any liquid.
A 38 millimeter ping-pong ball has been dropped into the pipe. You have to get the ball out undamaged. All you have is a long length of fine chain eg jewellers chain. How can you get the ball out?

Two teasers in one package
A man is tossing and turning in bed at night, unable to sleep. Finally he sits up, picks up the telephone by his bed, and dials a number. A voice answers. Without saying a word, he hangs up, but then (TAKES THE PHONE OFF THE HOOK), lies down (ON THE BROAD OF HIS BACK) and goes quickly to sleep. Why?
The first teaser is a popular classic. Simply read the above text but ignore everything shown inside the brackets in UPPERCASE. It has a fairly "standard" solution although you will probably find alternative solutions which also fit the facts.
The second teaser is my own variant. Read all of the words. Can you explain?

series-1
I wrote down 1 and doubled it and continued doubling it to produce the series
1 2 4 8 16 32 64 etc
Again I wrote down 1 and by using a simple mathematical method produced the same doubling series BUT with an extra 1 at the start, thus
1 1 2 4 8 16 32 64 etc
What did I do?
top answer

series-2
The Fibonacci series produces the next number in the series by adding together the previous two.
I often think it ought, therefore, to start with 0 1 rather than 1 1,
Thus: 0 1 1 2 3 5 8 13 21 etc,. What do you think?
Anyway, to my puzzle:
Here is the normal 'Fib' series: 1 1 2 3 5 8 13 21 etc
Here is the series I mentioned above BUT this time I did not create it by the method I described there.
0 1 1 2 3 5 8 13 21 etc
What did I do?

Napkin-ring puzzle
serviette ring
I have this silver napkin-ring (aka serviette-ring). It is a hollow pipe 4 centimeters diameter by 4 centimeters long. The metal is about 1˝ millimeters thick. The ring has a raised ornamental pattern which makes the outside slightly convex.
The ring containing a napkin was lying on the dining table. I slipped the napkin from the ring leaving the ring in its original position on the table.
Now, here is the puzzle: Suddenly, the ring which had been lying horizontally was standing vertically on the table. It had turned 90 degrees. How come?
I had not picked it up and turned it. Nor had I slipped my finger into the pipe and lifted it so as to tip it upright. Nor had I pushed from above to roll it over into an upright position. In fact, at all times my hands (ie fingers) remained in contact with the table. I used nothing to assist me, not even the napkin. What did I do?

Hanging by a thread
A mountaineer is descending a mountain by abseiling down its vertical cliffs (ie by sliding down a rope). He stands on a ledge where he finds a convenient rock spike over which he places his rope. The rope is 200 feet long and so hangs 100 feet down either side of the rock. He grasps both halves of the rope simultaneously, edges over the ledge, and slides down to the next ledge about 90 feet lower. He then recovers his rope from the rock above by pulling on one end. He attempts to repeat the process to descend the next cliff.

Again, he finds a rock spike over which he drapes his rope but the cliff is nearly 190 feet high and there are no holds part way down the cliff, so he cannot use his usual method. If he ties the rope to the rock he could slide down the single rope. This would mean abandoning his rope, but he needs the rope for the cliffs further below. What is he to do?

Instant pentagon
Because I needed a sheet of paper slightly shorter than A4 I tore a 1" wide rectangular strip from one end.
I was absent-mindedly playing with this strip when suddenly I found I had folded it into a regular geometrical figure. After trimming (or folding) away the excess paper there was a perfect pentagon. Amazing! What did I do?

Hamlet haiku
I have an addiction to Shakespearean plays and poetry and puzzles and have combined all three to present the result here as a haiku poem puzzle. Will the answer when it is finally discovered (or revealed) prove to be, or not to be, unquestionable?

To be, or not to ...?
Why can't I recall what's next?
That is the question.

Does the third line refer to the first question or the second?

Flying a 'Super Conny'

Super Constellation

The Lockheed 'Super Constellation' passenger plane was introduced in 1951 and became the world's best airliner. 129 passengers - 530 km/hr - 4 propellor engines. A sleek aircraft easily recognisable because of its distinctive 3-finned tail. Used as Air Force One by President Eisenhower.

Rule 23 of Instructions for Flying a Lockheed "Super Constellation" reads
'Pilots will not wear [........] when flying.'

What is the missing 'something'?

Voltaire: "Judge a man by his questions rather than by his answers."
Consider this quotation to be a truth. I am asked if I agree or disagree. I answer, "I agree with Voltaire, but what do you think of his quotation?" Because my answer is true [ie, it agrees with a declared truth], it ought be deemed good judgement and therefore superior to any question. But this disagrees with the quotation. Although I pose the quite sensible yet superficial question 'but what do you think of his quotation?' it seems quite inferior for judging me when compared to my assessment of Voltaire's 'truth'.
Alternatively, I could have answered, "I disagree with Voltaire, but what do you think of his quotation?" This answer shows lack of judgement. But is that to be ignored when judging me simply because I follow up by asking a trivial question? Ought I be judged on that triviality? Voltaire's quotation would seem to demand "Yes!"
I'm not sure where I stand with Voltaire. When I agree with him he would seem to disagree with me yet when I disagree with him he would seem to disagree with that, too. I can't win!

Puss poem puzzler
Haiku are poems, originally Japanese, which, in basic form, consist of 17 syllables arranged in three lines of 5, 7 and 5 syllables respectively. Some are quite beautiful. They also lend themselves to fun. Here are the first two lines of a haiku by Adaline More. You are asked to add the third line and answer both questions.

Bookworm goes hungry

bookworm

On a public library shelf, standing upright, are four books consisting of Volume 1 and Volume 2 of a 1st Edition and Volume 1 and Volume 2 of its 2nd Edition. Each Edition has 1000 pages with each Volume being of 500 pages.

A hungry Bookworm, for his lunch, eats a worm-hole from page 1, Volume 1, Edition 1 to page 1000, Volume 2, Edition 2.
That night, Bookworm tells his friend Logiworm about his lunch. Logiworm points out that had Bookworm thought logically he could have eaten twice as much by eating his wormhole from page 500, Volume 1, Edition 1 to page 501, Volume 2, Edition 2. Bookworm cannot see the logic of that argument but says he will follow Logiworm's method for tomorrow's lunch.
The next night Logiworm asks Bookworm, "Did you enjoy you nice big lunch, today?"
Bookworm replies, "No! I did not! I did exactly what you told me to do and I haven't had a bite to eat. I'm hungry! So, please, don't talk to me about logic!"

Fishy tale
Here is an easy puzzle that you can find in many places on the web:

There are two different plastic jugs filled with water. How could you put all of this water into a barrel, without using the jugs or any dividers, and still tell which water came from which jug?
Using that puzzle as a starting point, I have created this new one:
There are two buckets, one filled with fresh water with a fish in it and one filled with sea water with a fish in it. All of this water was put into a barrel, without using the buckets or any dividers. Each fish remained in its own water. I then went fishing in the barrel and caught both fish.

Hijacker's parachute
An armed man hijacked a plane and demanded $100,000. After he was paid, he ordered the flight attendant to bring him two parachutes. As soon as he had them he put one on and threw the other aside.
He was about to jump from the plane, when he stopped, took off the parachute and ordered the attendant to put it on and told her she was going to have to jump from the plane.
Only moments before the attendant was about to jump the hijacker stopped her, ordered her to swap parachutes and then jump. After she had jumped, he put on the other parachute and then he jumped.

Why did he apply such a strange sequence to escape with the money?
