Two people ate meat that was grown in a lab. It is the first time anyone has done this. It was part of a $380,000 project run by Google boss Sergey Brin. Scientists took two months to grow 20,000 tiny pieces of meat from a cow's stem cells. They added salt, egg, breadcrumbs and other things in the burger. Mr Brin hopes we will eat lab meat in ten years. He doesn't want animals killed for food. He thinks this meat is good for the environment.

Two food experts tested the beef burger. A chef fried it in sunflower oil. Food scientist Hanni Rutzler said it was "close to meat" but it "lacked juiciness" and was a little tough. Writer Josh Schonwald said it was a little dry because it had no fat, but was like a real burger. Many journalists wanted a taste, but there was only one burger. Researcher Mark Post said his children would get any leftovers. Cells from one cow can produce 175 million burgers.
