Hard Boiled Kiwi Bird Eggs

If you can hard boil a Kiwi bird egg in 20 minutes, how long would it take to hard boil four Kiwi bird eggs?
Note: Kiwi birds are about the size of a chicken, but they lay eggs that are close to the size of an Ostrich egg. So one would assume they must take a long time to hard boil.

20 minutes. You can boil them all at once in a large pot.

Canaries in the Cage

I am the owner of a pet store. If I put in one canary per cage, I have one bird too many. If I put in two canaries per cage, I have one cage too many. How many cages and canaries do I have?

Four canaries and three cages.

If you put one canary in each cage, you have an extra bird without a cage. However, if you put two canaries in each cage then you have two canaries in the first cage, two canaries in the second cage and an extra cage.

Almost Catching Fire

People come and watch, from far away to see
Burning brightly, almost catching fire,
The colder it is the hotter I’ll be.
Then I die.

What am I?

Fall leaves changing colors. “Burning” with bright colors, when it’s cold outside the brighter the colors are.

Wily Winifred and the Case of the Odd Numbers

Mrs. Shine was having a rough day and wanted a break. So she asked her class to calculate the sum of the first 50 odd numbers. In a few moments, Winifred was at her desk with the correct answer of 2,500. Stunned, Mrs. Shine figured she must have gotten lucky, and sent precocious Winifred back to her seat with the task of finding the sum of the first 75 odd numbers. Again, Winifred returned in seconds with the correct answer (5,625).

How did Winifred find the answer so quickly?

Winifred, being the precocious child she is, realized there was a pattern when computing smaller sums of odd numbers.

First 3: 1 + 3 + 5 = 9
First 4: 1 + 3 + 5 + 7 = 16
First 5: 1 + 3 + 5 + 7 + 9 = 25

Do you see the pattern like our dear friend Winnie?

For the first n odd numbers, the sum is equal to n2. Thus the first 50 is 502, or 2,500, and the first 75 is 752, or 5,625.

Never Ahead, Ever Behind

Never ahead, ever behind,
Yet flying swiftly past;
For a child I last forever,
For adults I’m gone too fast.

What am I?

Numbers Night Club

A man wants to get into a night club where the bouncers test each person before they can enter. The man waits and watches.
A woman walks up to the bouncers and the bouncers say 6. The woman replies with 3 and goes in.
A small man walks up and they say 12. The man replies 6 and is admitted.
The first guy thinks he’s figured it out and walks up. They say 4 and the man replies with 2, but they don’t let him in.

What should he have said?

4. The answer is the number of letters in the number. Six has 3 letters, twelve has 6 letters and four has 4 letters.

I Can Kill People

I can kill people, or cause great pain.
You eat me.
I can mean you’re crazy.
I hold things together.
I help climbers stay safe.
I can replace a swear.
And I’m on a violin.

What am I?

Nuts.

People with nut allergies can die from eating nuts. Being hit in the nuts hurts (I speak from experience. Painful, painful experience). You eat nuts (unless you’re allergic, in which case you should run away). If someone says you’re nuts, it doesn’t mean you’re a peanut or an almond. Nuts and bolts hold things together. A climber’s nut or chock wedges into a rock. Instead of swearing, you can say, “Aww nuts!”. And finally, the nut on a violin is a small piece of hard material that supports the strings.
