How can a bird egg be preserved as a specimen permanently? Kneel down and thank you first

The eggs laid by birds are also known as eggs. Different birds lay different eggs, not only in different sizes, but also in different colors and spots on the surface. Once the eggs are made into specimens, they can be stored for a long time.

Collecting a wide variety of bird egg specimens is not only a pleasure, but also helps us identify a variety of birds.

Tools & Materials.

Syringes and needles. Bird eggs (eggs, duck eggs), glue, bleaching powder.

Activity process 1: Buy fresh bird eggs (such as eggs and duck eggs).

2. Gently poke a small hole with the tip of a needle at the end of the small end of the egg and insert a thin plastic tube.

3. Blow air into the eggshell through a small plastic tube to blow the egg yolk apart, so that the egg yolk and egg white are mixed into a uniform liquid.

4 Use a syringe without a needle to draw the liquid inside the eggshell through a small hole in the eggshell or use a syringe with a needle to slowly inject air into the egg with the hole facing downward. The air exerts pressure on the egg whites inside the egg, causing the egg whites to flow out from the orifice.

5. After pumping the liquid in the eggshell, inject 10% bleaching powder solution into the eggshell with a syringe for 10 minutes of antiseptic treatment.

6. Pour out the bleach powder solution from the small hole, inject water into the syringe to clean, then pour out the water and dry in the shade.

7. Apply glue to the end of the eggshell hole, stick it to the vial cap, and then glue the vial cap to the wooden board or cardboard. Finally, attach a label with the name of the egg to the side of the egg.

Description & Extension.

1. The key to making bird egg specimens is: keep the eggshell intact and completely remove the egg yolk and egg white that are easy to deteriorate in the eggshell.

2. Bird egg specimens must maintain intact eggshells and original colors. If you make a large number of duck egg specimens, you might as well use colored pens to draw various Peking Opera masks on the outside of the eggshell, and it will become a beautiful easter egg.

3. If the eggs used to make the specimen are fresh and the syringe used is also clean. Then, the yolk and egg white that are pumped out can be burned and eaten.

4. Although there are many types of birds, and the size and color of the eggs vary greatly, the structure of the eggs is the same. The outermost layer of the egg is a layer of calcareous shell, and the yolk inside hangs from the egg membrane by the frenulum at both ends, suspended in the egg white. Under the action of gravity, the placenta on the yolk is always upward, and it is easier to accept the heat transferred to the parent bird when it incubates the eggs.

This is beneficial for hatching.

Drop a drop of ink on the table and place the egg, which is the center of gravity of the egg.

Make a small hole with a sharp instrument at the center of gravity, and shake out the egg white from there;

Puncture the yolk membrane with a needle and carefully dilute it with some water;

Shake out the egg yolk liquid;

Note: Clean the inside of the eggshell with water several times;

Inject dilute gypsum liquid into the opening to strengthen the thickness of the shell;

The openings are facing down to cool dry;

Keep tightly sealed. Note: Do not wash the shell of the egg, as some kinds of eggs may be washed off!

The Shanghai Composite Index is compiled based on the total number of listed companies, and the number of shares issued. That is to say, if you buy all the weights in the Shanghai Composite Index at the same time and hold them all the time, then your wealth will grow by the same extent as the index.

In the process, since the number or the number of ** are changing, then the weights are also constantly changing. You'll need to keep your portfolio in line with the changes in the index. This simply doesn't work in reality.

Regardless of whether the market is efficient or not, assuming that there was a ** of the Shanghai Composite Index before, and you buy the ** contract, then the correlation between your wealth and the stock index is of course 1. Moreover, it is margin trading, if the delivery period of this is more than ten years, you can hold it all the time, and your wealth can grow dozens of times from the basis point to the present.
