Every spring, without fail, some local television station runs a story on the first day of spring showing school children trying to stand eggs on end. Because, as the talking heads say, the gravity of the Sun lines up with the Earth's magnetic field.
It is all a lie. Everything you see in regards to that is a parlor trick, and just an excuse for the teachers to stop teaching for a few hours and get outside on the first day of spring.
You can learn all about it here.
In short, there is nothing special about the first day of spring, and it's an old wive's tale.
My grandmother used to tell me all sorts of old wive's tales. My favorite was the one that if you can put salt on the tail of a bird, it won't be able to fly, and you can pick it up. I remember as a small boy running around the yard of my grandmother's with a salt shaker trying in vain to catch some poor Robin unsuspecting so I can shake some sodium chloride on his tail so I could pet him.
But that doesn't mean it's true.
