Doesn't an egg stand upside down today? And you can see down a well at noon?
You're thinking of the equinox. Equal amounts of daylight and dark. The earth's axis is parallel to the sun. Happens in March 21st and September 21st.
The egg thing is a parlor trick. (See Casual's post above.)
The well thing only happens at the equator. For the rest of us above the equator the sun never makes it straight up at noon.
Ok, Mr Wizard.
I did go to college. It was called a joke. :Smiley_wink:
