"What is as light as a feather, but even the world's strongest man couldn't hold it for more than a minute?"

Whoever gets it right can post the next puzzle :lol:

A piece of wet sodium metal?

I'll give you that Fuzzy - the answer google gave was "his breath" ;)

Fuzzy's Turn :D

Nope :)

Fuzzy's Turn :D

That's actually not what I meant but "his breath" makes a lot more sense. I like that!!!

Ok, it's not exactly a puzzle but I heard this on a youtube lecture on human behaviour theory:

What did all these situations have in common?

1. A woman having her periods
2. A man with a brain tumour
3. An athlete on anabolic steroids
4. Binge eating

2. A man with a brain tumour
3. An athlete on anabolic steroids
4. Binge eating

They were all in pain? :grouphug:

(periods give cramp, brain tumour could cause a headache, athlete could be trying to improve his or her preformance and end up causing him/herself pain and binge eating could be caused by emotional pain) :grouphug:

Abi
06-23-15, 06:54 AM
I could hold my breath for 4 minutes in my teens (before I started smoking)

Abnormal moods/behaviour

4mins???? Did you practice????

Abnormal moods/behaviour

Both answers are correct but not what I'm looking for....

Ok, let me try to narrow this down a bit: "All four situations were used as an excuse for -- ??"

Fuzzy I didnt practice.

I just managed 1 min 5 secs even wih my smoke infested lungs.

Fuzzy12
06-23-15, 12:07 PM
... for killing someone?

YES!!!! :yes:

They were all used as defense in court for murder!!

Abi, I think, the few times that I've tried holding my breath I get max up to 40s or so after that it just becomes too unpleasant. :rolleyes:

I remember, as kids, we used to play who can hold their breath for longest. I remember once impressing my brother's friends massively by holding my breath for ages (((... by breathing through my nose))):lol:

I like that, but it's not the one that was listed in the answer section.

Half a point for that. ;)

Nope, neither of those is the right one. But you're both half-right.

Lunacie
06-23-15, 03:28 PM
3. Moral support

:yes: That's the right one!

Abi got the most right (3 out of 4) so it's his turn if he wants to go again.

A lift is on the ground floor. There are 4 people in the lift including me.
When the lift reaches 1st floor, 1 person gets out 3 people get in.
The lift goes up to the second floor, 2 people get out 6 people get in.
It then goes up to the next floor up, no-one gets out but 12 people get in. Halfway up to the next floor up the lift cable snaps, it crashes to the floor. Everyone dies in the lift. How did I survive?

Luvmybully
06-23-15, 09:31 PM
You were one of those that got out on the 1st or 2nd floor

Abi

A house has 4 walls. All of the walls are facing south, and a bear is circling the house. What color is the bear?

Lunacie
06-23-15, 09:54 PM
It's a white polar bear because in order for all four walls to face south you're at the north pole.

Luvmybully
06-23-15, 09:58 PM
Well done Lunacie!

Correct

Lunacie

ABI's youth lasted one sixth of his life. He grew a beard after one twelfth more. After one seventh more of his life, he married. 5 years later, he and his wife had a son. The son lived exactly one half as long as his father, and ABI died four years after his son.

How many years did ABI live?

How many years did ABI live?

S =1/2 a
A= s+4

S= 1/2s + 2

1/2 s = 2

S= 4


Abi = 8

?????

:lol: I guess that's wrong :D

What does this mean: the son lived exactly one half as long as his father?

Abi
06-29-15, 06:26 PM
Fuzzy it means like for example if I lived to be 80, my son lived to be 40.

midnightstar
06-29-15, 06:26 PM

I think it means that if the father lived for 60 years the son lived for 30 years longer??? Could be wrong on that and I'm typing round Tigger now

(apparently my hand is something to eat)

Fuzzy12
06-29-15, 06:32 PM

Dee Septor, the famous magician, claimed to be able to throw a ping-pong ball
so that it would go a short distance, come to a complete stop, and then reverse
itself.

He also added that he would not bounce the ball off any object, or tie anything
to it. How could he perform this trick?

You can't be wearing a white hat...so that means you're wearing a black hat.

I don't know how to write this out. It's more of an image in my head than it is words haha.

Albert is at the back of the line and therefore can see Barry's and your head since you're both in front of him. Barry can only see your head.

If you and Barry were both wearing a white hat, then Albert would know for sure that he was wearing a black hat. If you were wearing a white hat, and Barry was wearing a black hat...Albert wouldn't know if he himself was wearing a black or a white hat so he'd tell the guard he didn't know...which in turn would give Barry enough information to know that he himself was not wearing a white hat, which could only mean that he was wearing a black hat...which then gives you enough information to know that your hat too has to be black.

Albert was honest by saying he didn't know what color his own hat was, and Barry was rational in lying about not knowing his own hat color because he knew it'd give you enough information to get the correct answer...freeing all 3 of you.


....
or else I'm completely wrong and just made a complete idiot of myself haha.
I didn't sleep last night! >.<'

Psycho reaches the final destination in his quest of finding the hidden treasures. The final destination has two doors - one leads to the treasure and the other leads to a deadly maze that ends only at death. The doors are protected by two guards. Both of the guards know the correct door that leads to the treasure. One of the guards never speaks a lie and the other always speaks a lie. But the sad part is that there is no way Psycho can identify who is the liar and who speaks truth. Also the guards allow only one question to be asked to any one of the both.

What question will Psycho ask and to whom to finally get the treasure he has been searching for?

But the sad part is that there is no way Psycho can identify who is the liar and who speaks truth. Also the guards allow only one question to be asked to any one of the both.

What question will Psycho ask and to whom to finally get the treasure he has been searching for?
Ask left guard if I ask right guard if treasure behind right door what will right guard say

Right treasure, right guard yes, left guard says no

Left treasure, right guard no, left guard says yes


Is it:

ask one guard: "if I ask the other guard if the treasure is behind one of the door(I point to the door) what will the other guard say?"

Correct

Fuzzy12
07-02-15, 03:27 PM
Correct

What do you do with the response?

If the guard I ask says "no" then the door I point at leads to the treasure.

If he says yes then the door I point at contains the death maze.

This is challenging , and haven't solved it yet myself.

Suppose you're in a hallway lined with 100 closed lockers.

You begin by opening every locker. Then you close every second locker. Then you go to every third locker and open it (if it's closed) or close it (if it's open). Let's call this action toggling a locker. Continue toggling every nth locker on pass number n. After 100 passes, where you toggle only locker #100, how many lockers are open?

Answer
Answer: 10 lockers are left open:
Lockers #1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Each of these numbers are perfect squares. This problem is based on the factors of the locker number.
Each locker is toggled by each factor; for example, locker #40 is toggled on pass number 1, 2, 4, 5, 8, 10, 20, and 40. That's eight toggles: open-closed-open-closed-open-closed-open-closed.

The only way a locker could be left open is if it is toggled an odd number of times. The only numbers with an odd number of factors are the perfect
squares. Thus, the perfect squares are left open.

For example, locker #25 is toggled on pass number 1, 5, and 25 (three toggles): open-closed-open.

After pausing a moment, he replied, "Well! If I divide the coins into two unequal numbers, then 1000 times the difference between the two numbers equals the difference between the squares of the two numbers."

The wife looked puzzled. Can you help Abi's wife by finding out how many gold coins they have?

(A-b)*1000=a*a-b*b
A~=b
A+b=x



1000a-a*a= b*b-1000b

A(1000-a)=b(b-1000)

1000a-1000b=a*a -b*b = (a+b)(a-b)=1000(a-b)

A+b=1000

Abi has got 1000 coins :D

You pick a fruit from one of the boxes, see what the fruit is, put both labels that it could be by that box, pick a fruit from the next box, see what that fruit is, decide which label needs to be near that box and do the same for the third box and if you're allowed to pick more than one fruit from the boxes you can see which box has the two different types of fruit in :D

2. Defraud; violate rules -> Thermal energy in transit
3. Sensation of cold -> Local land elevation
4. Go upward -> Jointed appendage; branch
5. Strong metal rope -> Having necessary skill
6. Confined; restrained -> Old; grew older

She already knew she needed to fill 55 bowls of the same size and capacity with the same amount of food. When she was done, she decided to read the guidelines for the picnic, just out of curiosity. The guidelines said:

1. Every camper gets their own bowl of soup.
2. Every two campers will get one bowl of spaghetti to share.
3. Every three campers will get one bowl of salad to share.
4. All campers are required to have their own helping of salad, spaghetti, and soup.

After some rapid calculations, Margaret was able to figure out how many campers were going to the picnic. Can you?

Call the number of campers n.

n/1 + n/2 + n/3 = 55

(3n)/1 + (3n)/2 + (3n)/3 = 165

3n + 1.5n + n = 165
