that would help an egg balance. Standing an egg on its end is something just about anyone can do any day of the year. The feat simply takes the right egg, a little practice, and a lot of patience.

Earth’s axis of rotation is tilted about 23.4 degrees relative to Earth’s orbit around the sun
. This tilt drives our planet’s seasons, as the Northern and Southern Hemispheres get unequal amounts of sunlight over the course of a year.
