Optical Illusion

Recently a friend of DIT, who is a verrrrry smart student, sent us a text saying that she had read ALL of the DITs since the very beginning!

ALL !!

Now that is astounding. And huge Kudos to her !!! 

Wow Wow Wow.

Further more she said that her brother, who also is very smart, loved brain teasers.

One of his favorites is: 

"If it takes six men one hour to dig six holes,
how long does it take one man to dig half a hole?"

Ponder that and see what answer you get. 

I will post the answer at the bottom of this DIT so you can check.

In the meantime for him and for his sister, and of course for you, too, we have an interesting DIT about optical illusions.

As noted in the write up accompanying the video to which we are linking today,

"Many of the truths we cling to depend greatly on our own point of view."

This video is a real example of that saying by Obi-Wan Kenobi.

So rather than go on and on about this video and Optical Illusions, see for yourself.

HERE'S THE LINK to brain exploding optical illusion

And for the answer to the brain teaser noted above -- it is

 "there is no such thing as a half a hole."
