Choose a good egg suitable for carving: don't choose an egg with uneven surface.

It is best to have a smooth surface and a shape like a water drop.

Draw a small circle at the bottom (round end) of the egg, then carve it gently with a knife, and carve 1 hole on the eggshell by using the secret technique of "turning the egg without turning the knife".

After making a hole, make a small hole in the side of the eggshell.

Then the egg liquid is blown out by using the principle of air convection.

Put about 7 minutes of clear water in the egg and shake it up and down, then pour out the water and wash it several times.

Use a small brush to go deep into the eggshell for deeper cleaning, otherwise the egg will stink and become a "rotten egg"!

After cleaning, the egg hole will naturally dry in the shade for half a month. Sunbathing or using the oven is not allowed. When the eggshell and egg membrane are naturally combined, they will become stronger and suitable for carving. (The answer comes from the Internet)
