/sci/ - Science & Math

I found some methylene blue in an old science kit guys.

I pose a moral question-

Should I trick-feed it to my friends and watch them freak out as their urine turns blue?

I'm having some "ethical" difficulties. They might think I'm trying to date rape them. I don't really want to deal with the backlash if they lose their minds if I were to be caught (there are other reasons I'm too lazy to list). Then again I think my more paranoid friends need to be taught a lesson.
