Two Fuses

You have a lighter and two fuses that take exactly one hour to burn, but they don’t burn at a steady rate. For example, one fuse could take 59 minutes to burn the first inch and then burn the rest of the fuse in the last minute.

How would you use these two fuses to measure 45 minutes?

Light the first fuse on both ends and the second fuse at only one end. When the first fuse burns out you know 30 minutes have passed. Light the other end of the second fuse and when it burns out, 45 minutes have passed.

I Am Both Safe and Secure

As a whole, I am both safe and secure.
Behead me, I become a place of meeting.
Behead me again, I am the partner of ready.
Restore me, I become the domain of beasts.

Stable. A table is a place of meeting. Able and ready is a common phrase, and a stable is where beasts reside (beasts of burden, not beasts like the one in Beauty and the Beast who lived in a glorious castle but the west wing was forbidden to enter until Belle…I’ve said too much!).

I See Much But Change Little

I see much but change little,
I am firm, irresolute,
Powerful but gentle,
I can rip apart mountains,
Yet be moved by gentle stirrings,
I am valued and wasted,
I am life itself,
And I give life to others.

What am I?

A tree. A tall one can see long distances but don’t change much. They are strong and powerful, and the roots of a tree can slowly tear apart a mountain. The gentle stirrings of the wind can blow their branches and leaves. Trees are valuable as they provide wood and paper, but they are also wasted. And lastly, trees, like all plants, provide us with life-giving oxygen.

Crazy Taxi Driver

A taxi driver runs through four red lights, two stop signs and goes through a house. A police officer witnesses this but doesn’t do anything. Why not?

The taxi driver is not in his cab, he’s out for a run. The house he went through was his own because he was done running.

Animal Kingdom Quiz

This is a four-part brain teaser.

1. How do you put a giraffe into a refrigerator?
2. How do you put an elephant into a refrigerator?
3. The Lion King is hosting an animal conference. All the animals attend except one. Which animal doesn’t attend?
4. There is a river you must cross but it is used by crocodiles and you don’t have a boat. How can you cross safely?

1. Open the refrigerator, put the giraffe in and close the door. It’s not complicated.
2. Open the refrigerator, take out the giraffe, then put in the elephant and close the door.
3. The elephant. He’s still in the refrigerator. After all, you just put him there.
4. Jump into the river and swim across. The crocodiles are at the Lion King’s animal meeting.
I admit, this is not a typical brain teaser, but it amused me.
