The Messy Lab That Saved Millions

The Messy Lab That Saved Millions A scientist forgot to clean up before his holiday. And that mistake saved millions of lives. This really happened. London, 1928. Alexander Fleming studied germs, and his lab was famously messy. Before going on holiday, he left a stack of dishes full of germs on his bench. When he came back, he noticed one dish had grown a spot of mould. And all around the mould, the germs were gone. Something in the mould was killing germs. He called it penicillin. For years, almost no one paid attention. It was very hard to make. Then other scientists found a way to make it in large amounts, just in time to save soldiers and patients. Infections that used to be deadly could now be cured in days. It has saved millions of lives. That's Alexander Fleming. Sometimes a little mess changes the world. Comment MOULD.
