What are the techniques for standing an egg upright during the Spring Equinox? How to stand an egg upright during the Spring Equinox?

The Spring Equinox becomes the best time to play the egg-standing game, hence the saying "When the Spring Equinox comes, the eggs are pretty." The upright egg looks so beautiful. The gameplay of the "Egg Standing" game is simple, easy and fun. Although there are many failures, there are also many successes. So, what are the techniques for standing eggs upright during the Spring Equinox?

What are the techniques for standing eggs upright during the Spring Equinox?

1. Choice of eggs

Choose a smooth and symmetrical fresh egg that has just been laid four or five days ago. It should not be stored for too long. For eggs that have just been laid 4-5 days ago, the yolk band relaxes, the yolk sinks, and the center of gravity drops, which makes it easier for the eggs to stand upright. When standing eggs upright, do not choose cooked eggs or refrigerated eggs, because the yolks of these eggs are solidified and cannot sink, making them difficult to stand upright. If the eggs have just been taken out of the refrigerator, it is best to warm them up before testing. In addition, you should choose eggs that are big at one end and small at the other. When standing the egg, place the big end facing down. This way, the center of gravity will be lower, like a tumbler, making it easier to maintain balance.

2. Three points determine a plane

According to experience, the egg should be stood upright like this: the surface of the egg is actually uneven, with many protruding "hills". Each "hill" is about 0.03 mm high, and the distance between the peaks is 0.5-0.8 mm. According to the principle of using three points to determine a plane, as long as we find three suitable "hill" fulcrums, we can make the egg stand upright.

3. Be careful and patient

It is easier to make the egg stand up if you are careful and patient. The more impatient you are, the less likely you are to succeed. When standing an egg on its end, be patient, concentrate on your fingertips, and try to keep them still. Allow the yolk to slowly settle to the bottom of the egg so that the center of gravity is low enough for the egg to remain balanced.

4. Keep your hands steady when holding it vertically

Since the position of the yolk in a raw egg will also affect the egg's standing condition, the hand holding the egg should be kept as still as possible, allowing the yolk to slowly settle to the bottom of the egg, so that the center of gravity will be low enough to keep the egg balanced.

The saying that the spring equinox egg can stand upright

Statement 1: Some people believe that this is a purely technical issue and has nothing to do with the vernal equinox.

Statement 2: Astronomical experts said that an egg can stand upright on any day of the year, and a standing egg can remain upright in an environment without any interference (theoretical environment).

Why can an oval egg stand upright?

In fact, although the eggshell is a curved surface, the part where it contacts the table is not a point. The curvature of the large end of the eggshell is relatively small. Thus, for a very small area, it is approximately a plane. This extremely small plane is sufficient as a support point to allow the egg to stand steadily. Someone once did a similar experiment. They placed an upright egg on carbon paper and then observed the contact surface between the egg and the carbon paper. It was found that the tips of at least three protruding points on the eggshell surface were stained with the color of the carbon paper. This is what scientists call the "tripod theory." Experts say that, in fact, an egg can stand upright on any day of the year. Citizens can try it at home: take a fresh egg, turn it upside down, and gently place it on the table. Carefully find the balance point and don't let go until it stops falling. Moreover, the eggs that stand upright can remain standing for more than ten days without any external interference.
