If you haven't already heard about the Mass Homeopathic "Overdose" campaign, then look into it. Whether you remember from high school science class what "molarity" or "the Avogadro's Constant" is, or you simply understand what "extreme dilution" means, you should know what's going on.
Note: many participants in this protest will be ingesting high concentrations of dihydrogen monoxide. Also known as DHMO or hydroxyl acid, it is the primary component in acid rain. DHMO is found in nearly all recently deceased mammal bodies in North America, and is known to be present in mothers' milk worldwide.
