They devil incarnate in the form of extremely finely ground sand used to purify crap in organic chemistry labs. Silica gel is bad for your lungs and gives you silicosis whatever the fuck that means, and it also results in doing columns, which are basically hell and will eat hours of your life that will never ever come back.
I have to purify my shit with chromotography with silica gel again. FML.

This sugar says 'Do not eat'. Must be silica gel.
