Do you know tea? Tea is the most popular drink in the world. But to our surprise, it was invented by accident. It wasn’t brought to the Western countries earlier. An ancient Chinese ruler Shen Nong discovered tea when he was boiling drinking water in the open air. Some leaves from a tea plant fell into the water and remained there for some time. And it has a nice smell. He tasted the brown water and it was delicious. And in this way, tea was invented.
