Equinox: refers to the two times each year when the sun crosses the celestial equator resulting in day and night being of equal length.
Well, we experienced that today thanks to a lady in the church. June 19th is the first day of summer and the start of the Dragon Boat Festival. We were able to balance an egg and cause it to stand on end. Not only did we get it to stand on both ends, but we also did it on a slightly slanted sidewalk! It was fun!! :o)
