I also included some relevant footage from the lab taken last year. In my lab footage, I flame dry a round-bottomed flask. It is positively beautiful to watch the eliminated water re-condensing on the cooler parts of the glass until the flask is completely dried. I was even able to weigh the dried flask as it slowly sequestered moisture from the atmosphere and gained mass, allowing me to approximate how much moisture was removed! Any instructors our there who are interested in using this footage in their classroom, please contact me through the form on my website for permission and a high-res video file!
Next up on my YouTube channel is a follow-up video about removal of water from organic solvents using molecular sieves.
