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.

Well, first it’s fire.

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.
