A two-liter soda bottle can be converted to a face shield.
- ALWAYS CLEAN AT LEAST THE OUTSIDE OF THE FACE SHIELD AFTER USE. Treat it like it might have viruses on it. Be careful where you put it until washing it. Soap up your hands and smear the soap over the face shield. Lots of soap and running water should be enough. That should wash viruses off like washing your hands does. The shield can be air dried or some other way.
