What's for dessert?

Another puzzle, yay! What do I want for dessert?

1. An element, a blue liquid you breathe.
2. The end of a sentence.
3. wgpz tzggjr wgvxf bmzzi mzy
4. It's three til' 4, plus forty more.

Hint:

Each clue relates to a number.

pi e = 8.5397... Well, who doesn't want pie for breakfast? In all honesty I figured out the pun first then made the clues match.

An element, a blue liquid you breathe.

Oxygen is atomic number 8

The end of a sentence.

Full stop/period, i.e. a decimal point. Note the hint said the answers /relate to/ a number, not are numbers

Caesar cypher key is 5. (giving "blue yellow black green red", as mentioned in previous answers)

It's three til' 4, plus forty more.

3 til 4 is 3:57, +40 = 3:97... Thanks to @hexomino in the comments for improving on my original answer.

• +1 Great answer, I would say the last clue is 3:57 = 357 + 40 = 397. What you say in the last line isn't entirely correct. Specifically, there are definitely more than 40 more but, interestingly, the general characteristic is not known. Jan 16, 2019 at 11:46
• Ah thanks @hexomino, that makes WAY more sense, I'll update with your improvement :) Jan 16, 2019 at 11:54
• Also, as @rhsquared said, the colors are the Olympic rings. There are 5 rings, 5 colors, and the shift is 5!

Partial Solution:

Line One:

Nitrogen - number 7 on the periodic table

Line Two:

A Period...maybe you want an ascii code?

Line Three:

blue yellow black green red - maybe hex codes?

Line Four:

537

• Aw, you got it wrong. It's kinda correct, though. ruggcf://lbhgh.or/cC44RCOZo8N?g=441

Partial:

1st line

Oxygen - atomic number 8, it's in air and also is blue when in liquid form

2nd line

As @Brandon_J said, period. Maybe that's the answer, just a '.' since it appears in decimal numbers

3rd line

translates to "blue yellow black green red" in ROT5, so 5 is the answer?

4th line

no idea so far

Partial:

An element, a blue liquid you breathe.

Both oxygen and nitrogen when liquid are pale blue liquids. It could be N or O with atomic numbers 7 and 8. Another point - they will be in molecule form so it's more correct to be N2 and O2 which makes the numbers 72 or 82.

The end of a sentence.

Full stop, . or period, ASCII CODE 46 (0x2E)

Rot5 gives us the colours of the olympic rings. Maybe it's the next olympic games in Tokyo in 2020, or it could be 1896, the year in which the moderl Olympics were restarted.

It's three til' 4, plus forty more.

3 till 4, that's 3:57 or 15:57 plus 40 more gives 4:33 or 16:33. Or it could be as @Flying_whale pointed, 3 to 4 that is an interval of 1, so the result is 41

other partial answer, based on Quantoss and Brandon_J assumptions
1

oxygen = 8

2

'.' ascii code = 46 or hex code is 2E

3

5

4

3 'til 4 is 1 or 7 "plus 40 more" either 41 or 47

then I think we should

use the leet alphabet to decypher, possibilities are:
846541 = babsai / babsal
82E541 = bresai / bresal
846547 = babsat
82E547 = bresat
6 can also be 'g'
none of them are dessert :(
