Lots of people try to balance eggs on the autumnal equinox - but is it actually possible?
It's time to dig out your scarf and start complaining that the days are getting shorter, because autumn is officially here.
The autumnal equinox takes place today marking the end of summer in the Northern Hemisephere.
And while many focus on the day's astronomical significance, some have a more bizarre challenge for the day - trying to balance an egg on its end.
But is it actually possible to balance an egg? And does the equinox make any difference?
Here's everything you need to know.
What is the autumnal equinox?
An equinox happens when the sun passes directly over the Earth's equator.
It results in a day and night that are exactly the same length.
There are two equinoxes every year, one in March marking the beginning of spring and the other in September kicking off autumn.
In the southern hemisphere the seasons are flipped, and the September equinox marks the start of spring.
Can you balance an egg on the autumnal equinox and why do people think it's a thing?
Many people believe it is possible to balance an egg on its bottom during an equinox due to the specific gravitational pull on that day.
And it's not just eggs. People also try to balance brooms on their end.
But it turns out it's always possible to balance an egg - and the date has absolutely nothing to do with it.
Don't believe us?
Our experiment, which can be seen in the video above, didn't exactly go to plan, but Kirk Mona of Secret Nature had a lot more success.
What happens on the autumnal equinox?
This year, the autumnal equinox takes place on Friday, September 22.
It is celebrated around the world, notably at the Aztec monument Chichen Itza in Mexico.
And of course, there are a lot of attempts to balance eggs...
