a credit card sized card titled CO2 content of the room's air. Below that is a bar that goes from green to yellow to red. In the green part it says up to 600ppm, the yellow part reads 1000 ppm and the red part says over 2000 ppm. Underneath that we see three face emojis. The green one is laughing, the yellow one looks worried, and the red one has two x for eyes and looks unhappy. Underneath that it says Your CO2 with some space for me to write that down and Date with some more space for me to put that day's date.

#YallMasking on weekends?
I took the kids and one of their friends to an indoor trampoline park. It is in an old warehouse or stable... CO2 was at ~1600ppm (room was full) but would dip any time someone would open the door.... Theoretically they could have great ventilation (windows up high on each end of the space but only one side was open...)
I left them a note on a little card that explains how CO2 impacts your wellbeing and performance. I was given a stack as a present from @keinhoernchen
