The face mask of the future
Bluetooth, in-built cooling, nanotech filters—as we learn to live with covid-19, what sort of transformation will the face mask undergo to adapt to human demands?
How effective is a face mask? In a recent tweet, Rich Davis, director of microbiology at the Providence Sacred Heart Medical Center in Washington, demonstrated the difference between wearing a mask and not wearing one with the help of a simple experiment. He sneezed, sang, talked and then coughed towards an agar culture plate with a face mask on. He then repeated the exercise without a mask. “What does a mask do? Blocks respiratory droplets coming from your mouth and throat…. Bacteria colonies show where droplets landed. A mask blocks virtually all of them." His tweet, which was accompanied by photographs of the culture plates, has garnered more than 334,000 likes.
