Wow! So much wrong. Why make potassium metal when it can be purchased? Why have such a large quantity of sodium metal? Better PPE and safety shielding needed. (His PPE varies in the video.) He appears to be working in a small space without adequate ventilation
(as evidenced by the "smoke" filling the area). Rather than "don't-try this at home", just DON'T TRY THIS!
While I was actively teaching, I had small quantities of lithium, sodium, and potassium metals to demonstrate their reactions with water to my classes. They were properly stored in heavy mineral oil. Only a very small piece of each metal was needed to demonstrate
the reactions with approximately 200 mL water in a 600 or 800 mL beaker covered with a fine mesh screen. The reaction was projected on a large screen in the front of the lecture room. There was little vapor generated from the reactions. The room had good
ventilation.

Subject: [DCHAS-L] YouTube Shorts interesting dangerous home experiments
Hello Everybody,
Sometimes I like to watch Mr. Green’s “don’t-try-this-at-home” science video shorts – for entertainment value only. It gives you the opportunity to figure out what went wrong, or what demos to avoid. In this case, I believe the quartz flask failed and allowed
oxygen to enter.
Thought I’d pass this link along – for your entertainment. There are plenty more where this came from!
