TIL animals may be allowed in chemistry labs. But then again, still remember my professor's being very clear that mouth pipetting is bad idea, to then show us how to do it just in case.

I ate cancer cells of a person who died 40 years before me trying mouth pipetting

I had a classmate that managed to dump nitric acid all over themselves doing that. Luckily it wasn’t strong enough to not be funny.

My chem teacher was also the lab instructor. He would talk about how gloves are important because of the permeability of human skin. Then next lab would put a drop of dcm on his hand. Still not sure why he did that. Maybe he was illustrating it having a fairly low vapor pressure¿
