The Myth:
“The ostrich buries its head in the sand.”

Breaking the myth:
Never has an ostrich who has buried his head in the sand hatched nor has the ostrich

The explanation:
Like us, the ostrich does not like sleeping standing up. When it sits down, its head and neck rest on its feathers. From far away it looks like a pile of feathers without a head. In actuality it looks the same way close-up.

The Myth:
“The setting sun does not hurt the eyes therefore; one is allowed to look at the sunset.”

Breaking the myth:
Boy is it harmful to look at the setting sun! And it is even more dangerous due to the lack of awareness which encourages people to look at a sunset for a long time. It is romantic.

The explanation:
The angle of the entry of the sunlight is indeed lower and is less direct. Therefore, the light decreases and creates the illusion of a lack of danger. But, just because of this, we look at it for a long time, our pupils dilate (due to the encroaching darkness) and thus endanger our eyes.

The Myth:
“The sky is filled with billions of twinkling stars.”

Breaking the myth:
On a clear night, with our naked eye, we are unable to see more than 3,000 stars. Everything else is a romantic myth in our imagination.

The explanation:
We are interpolating from our transmitted knowledge and from the knowledge received from large telescopes and have made deductions which seem reasonable to us, if only in our imagination.
