Which came first, the chicken or the egg... or the Saran Wrap? In the viral video below, a group of Japanese high school students take an egg, crack it into a clear sterile vessel, cover it in plastic wrap, and then place it into an incubator. After a few days, you begin to see a beating heart developing. Blood vessels spread through the yellow yolk, other body features begin to form, and before you know it you've got a little chick waddling around the lab. Too. Cute. The process is fascinating, though it may deter you from eating eggs for a while.
The technique itself is not new and wasn't developed by the high school students — that credit goes to the authors of a 2014 study in The Journal of Poultry Science. According to the study, the method only has about a 60 percent success rate. But it could still mean a lot for the future conservation of endangered birds (think surrogate eggs). Just don't try this at home, folks!
