Did you notice that in Breaking Bad? When the name "Breaking Bad" appears in the intro, two chemical symbols are shown: Bromine and Barium. However, neither of them is used to make methamphetamine. But if you look closely a few seconds earlier, you can see some text appear which says "Meth." Additionally, there is a chemical structure, C10H15N, which is actually the chemical structure of methamphetamine.
