It's a cool technique, but the video is dishonest in that the Chinese students were not the "first in the world" to hatch eggs "out of the shell." That is blatant plagiarism. Snopes debunks it as well:

The technique has been used many times for nearly half a century.
A high-school student at the time, Bruce E. Dunn was the first person to perfect the method in 1973, and he presented it as a science-fair project. The results and the method were published in a number of scholarly journals. I did an online search and found this book chapter (See Introduction, p. 106):

Here's a link to Dunn's article abstract where the technique was first published in
Poultry Science in February, 1974:

It's nice to know that
the kid grew up to be productive researcher and scholar:
