If you filter some buttermilk, you will get a solution of lactic acid and water. The lactic acid is what makes the milk sour.
I needed a very small amount of lactic acid to clarify microscopic organisms for study under my microscope.
So, I asked if the chemistry or biology departments of the school could spare 1 ml of this chemical. They could supervise their students using a pipette, as they introduced 0.3 ml of lactic acid into my prepared vials.
I got a lecture about illegal drugs and how they could never supply chemicals to anyone.
Lactic Acid?!?! Who do you think you are, Timothy Leary?!?!?!

I wish I could say, "I'm shocked," but I'm really not. It's depressing, actually.
