From Jonathan Arch
Reading about the manipulation of school science practicals reminded me of when, as an undergraduate, I and many of my classmates failed miserably in our quest to make p-nitroacetanilide – a chemical intermediate for some dyes. One day, somebody pointed out that the real stuff bears a remarkable resemblance to powdered milk. How easily the demonstrator was fooled!
