The Internet is Lying to You About the Broom Challenge
I see you posting your photos of brooms on Facebook and other social media. According to NASA, it's the one day where your brooms can be made to stand upright, correct?
Well, hear me now: try it again tomorrow, and the day after. Try it any day. If it works today, it should word any day. It's all a hoax, perpetrated for someone's enjoyment.
The hoax has long been around and is associated with the Egg Balancing Hoax. Eggs, like brooms, are supposed to be able to be stood up on end during the vernal equinox.
One of the problems with the #BroomChallenge is that it isn't even the vernal equinox! That doesn't happen until March 19th!
According to Encyclopedia Britannica, the vernal equinox is " two moments in the year when the Sun is exactly above the Equator and day and night are of equal length; also, either of the two points in the sky where the ecliptic (the Sun’s annual pathway) and the celestial equator intersect.
According to Snopes, the internet-hoax busting site, the broom challenge began in 2012 and seems to pop up once in a while.
