    They probably did this in a small classroom with doors and windows closed, and let the kids gather close. Should’ve used the gym.

      Interesting. I’m not sure exactly what they were doing.

      We made dry ice root beer multiple times in school. They weren’t super large class rooms but nobody ever got sick. I could see how having the dry ice submerged in liquid captures some of the CO2 and we didn’t need all that much anyways.

        “captured some of the CO2”

        Well, glad you did this multiple times and figured something out…

        Where do you think the carbonation came from? It is the C02. That was the whole point of the “experiment” smh. It’s even in the name of the word “carbon-ization”.
