The "How Not to Do It" category is also pretty good: https://www.science.org/topic/blog-category/how-not-to-do-it. My favorite is probably https://www.science.org/content/blog-post/not-do-liquid-nitr..., on what happens when a pressured liquid nitrogen tank blows up due to the pressure relief valve being closed.

I'm not sure why the "Things I Won't Work With" category/tag isn't working on the new platform; all other categories I checked seem to work, though I can't find a list of all categories.
