What comes first—the chicken or the egg? The age-old question has finally been answered. In Chiba, Japan, two Oihama High School students have successfully grown a chicken from an egg—outside of its shell.

The video below documents the 21-day experiment. The students broke open fertilized, brown, grocery-store eggs onto plastic wrap stretched over a cup.

They then fill both the plastic and the cup with a chemical solution to help the chick develop—another sheet of plastic is then stretched over the egg.

Afterward, the students poked breathing holes in the plastic so the embryo could get oxygen.

In the final step,  they placed the eggs in an incubator and waited for the miracle of life to show itself.

See the experiment in video below:

On the third day of incubation, the yolk developed a beating heart.

Five days later, to form an embryo, the blastoderm (a layer of cells formed at one pole of the yolk) developed and began to spread around the yolk.

After a week, the students were able to see the formation of veins around the yolk.

Upon three weeks passing, the real miracle occurred. A fully formed chick emerged from the plastic wrap and proceeds to run around the classroom in glee.

According to a scientific paper published in the Japan Poultry Science Association about the experiment, the chickens were bred to maturation, and they produced healthy offspring.

This wasn’t the first time in history that a chicken was born without its shell though. Back in 1993,  Dr. Cynthia Fisher detailed the entire experiment in a US biology textbook.

So now, we know what came first—the chicken!
