Plant-based meat alternatives like the 'Impossible burger' are all the rage right now, but scientists are already working on the next big thing - lab-grown meat.
The process, also known as 'clean meat', can take cells from something like a chicken feather, and grow them in the lab to make a steady supply of animal protein without killing any actual animals.
One of the major early investors in lab-grown meat is Microsoft founder Bill Gates. Some experts predict that in 20 years, half of our meat supply will be grown in a lab.
