sesh people this was made in 2012, people are not so fragile during those times, maybe he can't even be in the same room with a woman now in a fear of being accused.

Thank you for posting these, they are incredibly helpful! That said: I don't like that you called out to ladies for having to use muscle when grinding the leaves. We get enough flack in the lab as it is being surrounded by men and comments like these certainly don't help. It is sufficient to say that it takes significant effort. I typically wouldn't say something about this, but your videos set an example for students.

I totally agree!! Was just watching this video with my classmates, and we all noticed that (and were quite upset by it).

And the push harder comment seems to refer to birth labor. So sexist and inappropriate.

If you set the plate on a warm, not hot, hotplate and spot it there, the solvent evaps more rapidly and the spot spreads out less, allowing you to place additional spots.
