1/2 full 1/2 empty test.

[BoyntonStu]

When I was interviewed for a job, my interviewer gave me a test.

Here is a misshapen transparent bottle, some liquid in it, and sealed.

Proove to me that the bottle is half-liquid half-empty without breaking the seal.


I passed the test and I was accepted for the job.


What was my answer?


BoyntonStu

You could prove it useing displacement, if you had measuring containers.

without breaking the seal....


BoyntonStu

Displacement can be measured without breaking the seal, if you have an identical bottle.

Simply put the full bottle in a measured container, measure the displacement, then fill it to the same level as the first bottle, measure the displacement, and equate the difference.

When I was given the interview test for the job, I was handed the bottle and had nothing else available I had to come up with the answer in just a few minutes at the most.

Try again?


Boyntonstu

Turn the bottle upside down.

Just mark the filled-to line and turn it upside down. If the fluid comes to the same line, the bottle is half full.

Simple.


Boyntonstu

What bottle?

Oh, wait. That's to prove the bottle doesn't exist....
