Four Colored Balls in Gym Class

Four different-colored balls are being used in a gym class activity – blue, red, yellow and orange. Each student must hold two different-colored balls, but no two students can have the same two colors (for example, only one student can hold the blue and red ball).

How many students can play the game?

Six. If you prefer math, you can calculate it as 4 combination 2

4! / (2!)^2
24 / 4 = 6

Or you can work it out manually:

1. Blue Red
2. Blue Yellow
3. Blue Orange
4. Red Yellow
5. Red Orange
6. Yellow Orange

Pushing Car Past Hotel Lands You in Jail

A man pushes his car by a hotel and gets sent to jail. Why?

The man is playing monopoly, and landed on the Go To Jail space. An alternative version of this is, “A man stops his car in front of a hotel and immediately knows he is bankrupt.” The answer is the same, that he’s playing Monopoly, but this time he landed on a space with a hotel and didn’t have enough money to pay the bill.

I Go Around In Circles

I go around in circles,
But always straight ahead
Never complain,
No matter where I am led.

A wheel.

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?

Childhood.

You’ll See Me When the Sun is High and Also Late at Night

You’ll see me when the sun is high and also late at night,
I’m in the songs of holidays, when the snow is white,

Kings and Queens and royalty, are all found in me,
I’m the largest of them all, with just one you see,

Step by step with pounding feet, I’m tribes of angry men,
I’m above your hands right now, for help or to go again,

You’ll use me in the kitchen, or add a little more,
I’ll be in the years to come, and the days of yore.

What am I?
