Seen in the Water

I am seen in the water
If seen in the sky,
I am in the rainbow,
A jay’s feather,
And lapis lazuli.

Blue.

Days Before August 17th

How many days before August 17th is it, if fifty days ago, it was four times as many days since March 30th?

18 days or July 30th.

17 August – 18 days = 30 July.
30 July – 50 days = 10 June.
10 June – 30 March = 72 days, which equals 4 × 18.

Code in the Cold

Last winter I found myself locked out of my house because I couldn’t remember the 5-digit code to open the garage door. I used the following facts to get inside.

1. The second and third digits add up to 9.
2. The first digit is equal to the second digit cubed.
3. The sum of the third and fifth digits is the smallest number with exactly five divisors.
4. The fourth digit is equal to 6 times the second-to-last digit.
5. None of the digits repeat.

What was the code?

82709

If we label each digit a, b, c, d and e, we get the following equations.
1. b + c = 9
2. a = b3
3. c + e = 16 (since 16 is the smallest number with five divisors – 1, 2, 4, 8 and 16).
4. d = 6 * d (The fourth and second-to-last digits are the same number, meaning d must be zero to satisfy the equation)
5. b must be zero, one or two (b can’t be three because that makes a=27, which isn’t a single digit). Zero and one result in duplicate digits (00907 and 11808 respectively) so the only remaining value for b is 2, giving us 82709 and warmth.

Round Like An Apple

Round like an apple, deep like a cup,
yet all the king’s horses cannot pull it up.

A well.

Speaks Without Words

What is it that speaks without any words?
And can be loudly and distinctly heard?
Will drive away friend, and foe alike.
And is enough to make a stolid man’s face alight?

Flatulence.

Three Cuts to Turn a Round Cake Into Eight Equal Slices

How can you cut a round cake three times to make eight equal slices?

Cut #1 – Down the center of the cake (vertically) leaving two equal halves.
Cut #2 – Across the center of the cake (horizontally) leaving four equal slices.
Cut #3 – Through the middle edge of the cake slicing all four of the pieces in equal halves, leaving eight equal slices (four equal tops and four equal bottoms).

I’m Told and Make You Crazy

I can be told and can make you crazy,
Most people don’t like me and think I’m harmful.

What am I?

A lie. Lies are told, can make people crazy with rage, and most people don’t like to have lies told to them. Lies can’t be harmful though. :) (See what I did there?)
