Visibility of liquid particles coming out of the mouth without a mask and with a mask in a study published in New England

The green luminous pieces are the expelled liquid particles. In the case with the mask, almost no liquid particles come out.

This research shows that #mask_for_everyone can be a good solution to slow down the transmission cycle of the coronavirus..

Of course, our homemade masks may not be as efficient as the mask used in this research, but they definitely play a significant role in reducing the possibility of transmission by reducing the volume of the virus released from the mouth..
