  This image is a reference to things like this, where you send dry (containing low water content) solvent through a column of activated alumina to make it even more dry.

  It doesn’t really work as well with some solvents. The one I used in grad school had DCM, toluene, THF, and acetonitrile. If we needed dry DMSO, DMF, DMAc, acetone, MEK, or alcohols they had to come from a sealed bottle.

  I used to work at IBM. This guy is a classic case of manager brainrot and has filled the top few tiers of the company with the same. The only reason they make money is the rank and file know how to feed them trendy bullshit that makes them feel smart, which happens to also be a good way of separating other companies’ dumb C-suite types from their money.

  But even a blind squirrel finds an acorn every once in a while.

  Graduate students famously never make mistakes (like including their own hair in samples) and also never smoke weed. So that couldn’t be it.

  A redneck missing half his teeth can make meth in a Gatorade bottle in a Wal-Mart bathroom. I could probably figure it out. But that would be pretty bad for my career.

  As an actual professional organic chemist, ironically, these make my eyes hurt.
