A Big Rig Crossing a Bridge

An 18-wheeler is crossing a 4 kilometer bridge that can only support 10,000 kilograms and that’s exactly how much the rig weighs. Halfway across the bridge a 30 gram sparrow lands on the cab, but the bridge doesn’t collapse. Why not?

Since the bridge is 4 kilometers long, the halfway point would be 2 kilometers. The 18-wheeler would have used much more than 30g of fuel to drive 2 kilometers.

A Bottle and a Cork

A bottle and cork cost $1.10. If the bottle costs a dollar more than the cork, how much does the cork cost?

Most people guess 10 cents, but $1 more than 10 cents is $1.10, which would mean the total cost would be $1.20, not $1.10.

The correct answer is 5 cents. If the cork costs 5 cents, then the bottle costs a dollar more, or $1.05, making the total cost $1.10.

At Birth It Can’t Start Nor By Death Is It Ended

More precious than gold, but cannot be bought,
Can never be sold, only earned if it’s sought,
If it is broken it can still can be mended,
At birth it can’t start nor by death is it ended.

Friendship. It is more precious than gold to have a genuine friend, and true friendship cannot be bought or sold, only earned. When a friendship is broken it can be fixed and infants aren’t able to make friends until they’re older, but death can’t end it. Love doesn’t work as an answer because a friendship requires two people to interact, while parents love their children as soon as they’re born.

Waiting For a Man To Die

I cannot be other than what I am
Until the man who made me dies
Power and glory will fall to me finally
Only when he last closes his eyes.

A prince.

Turn Us On Our Backs

Turn us on our backs
And open up our stomachs
You will be the wisest of men
Though at start a lummox.

No Thicker Than Your Finger

No thicker than your finger when it folds.
As thick as what it’s holding when it holds.

A sack.

A Third of the Way But Only Halfway There

You’ve traveled a third of the way, yet you’re only halfway there.

Where are you going?

Hint: The answer applies in the US but not in Europe.

You’re in a build headed to the fourth floor. When you reach the second floor, you’ve gone one floor and have two more floors left, so you’re 1/3 of the way. But at the same time, you’re on the 2nd floor and have two more floors to get to the 4th floor, thus you’re halfway there.

This doesn’t work in Europe, because they typically refer to the “first floor” as the ground floor, and the first floor is one story up.

Thanks to Danny Llinas for submitting this.

Swiftest Traveling Horses

Two horses,
Swiftest traveling,
Harnessed in a pair,
And grazing ever in places,
Distant from them.

What am I?

Eyes.
