It took way longer than I wanted it to, but finally the second installment of the series is live. It took a while to receive all the pieces of my apparatus and a bit of trial and error, but I think the result is an interesting experiment. I originally planned on making all the noble gases into one video, but I had the idea for this experiment and had to try it. I think it makes for a more interesting video than just talking about the gas and showing an empty-looking ampoule!
Here's a link to a video on the % of O2 in the air experiment: https://www.youtube.com/watch?v=-28uuBcBK_E
