My Motor Revs, But I’m No Rocket

My motor revs, but I’m no rocket,
I’ll hit you deep within your pocket,
I’m a little tart, don’t be afraid,
Unless life’s gift – then quick, seek aid!

A lemon. It’s a citrus fruit whose juice is acidic and can be used to conduct electricity for motors. A car or other purchase that has problems is known as a lemon and can be expensive to repair. Lemons have a tart flavor but do little harm (unless you get it in a cut, then it hurts like the dickens). The old saying goes, “When life gives you lemons, make lemonade” (I know, it’s spelled aid not ade but it sounds the same and wouldn’t make any sense the other way. It all works out nicely when the riddle is told instead of read.)

The Longest Double Letter Word

What is the longest unscientific English word that uses every letter in the word exactly twice? For example, noon has two Ns and two Os, but it’s not nearly long enough.

Happenchance. There are two Hs, two As, and so on for all the letters in the word. The longest scientific word with the same property is probably esophagographers.

Two Hours Ago

If two hours ago it was as long after one o’clock in the afternoon as it was before one o’clock in the morning, what time is it right now?

9pm (or 21:00). There are 12 hours between 1pm and 1am, so 6 hours after 1am is halfway. 6 hours + 1pm equals 7pm. In order for 7pm to be 2 hours behind the current time, it must be 9pm.

Look In My Face

Look in my face and I am someone,
Look in my back I am no one.

What am I?

A mirror. The face of a mirror shows your face, but the back of a mirror shows nothing but dust and cardboard (depending on the type of mirror).

Sometimes I’m An Insult

Sometimes I’m an insult,
Sometimes I’m a meal,
But if you see me hanging around,
I hope to change how you feel.

A turkey.

The Bookworm

A bookworm eats from the first page of an encyclopedia to the last page in a straight line. The encyclopedia consists of ten 1000-page volumes and is sitting on a bookshelf in the usual order. Not counting covers, title pages, etc., how many pages does the bookworm eat through?

        __                             __
      B|  |                           |  |F
      A|1 |...........................|10|R
      C|  |                           |  |O
      K|  |                           |  |N
       |__|                           |__|T
      -------------------------------------

On a book shelf the first page of the first volume is on the “inside”, so the bookworm eats only through the cover of the first volume, then 8 times 1000 pages of Volumes 2 – 9, then through the cover to the 1st page of Vol 10 for a total of 8,000 pages.

Note: The question asks how many pages, not how many sheets of paper.

I’m A Sifter

I’m a sifter of a memorable shape,
You can eat a variety of me, but I can be toxic,
I can cause severe pain if you’re not careful,
And the action I describe could hurt as well.

What am I?

A kidney.

Kidneys filter your blood and are shaped like kidney beans, which you can eat. Red kidney beans contains high amounts of phytohemagglutinin (quite the word, eh?) and can be toxic if not soaked and boiled. Kidney stones can be extremely painful and if a kid knees you in the stones, that would also be unpleasant.
