    1. Dihydrogen Monoxide (DHMO) is a colourless and odourless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid. Its basis is the highly reactive hydroxyl radical, a species shown to mutate DNA, denature proteins, disrupt cell membranes, and chemically alter critical neurotransmitters. The atomic components of DHMO are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol.

    Ooh ooh! I got ’em all correct but was too slow, honest. Can I have Swinson please? If she identifies as a filly I could ride her in the Epsom Oaks.

      But she identifies as a monumental hypocrite, trading under the title of ‘Liberal Democrat’ when her democratic credentials are utterly false. Can you be sure if she identifies as a ‘filly’ that she’s not hiding some stallion-tackle? I wouldn’t take the chance, or you may end up taking it via the ‘tradesmen’s entrance’.

    Oh, isn’t it moments of madness which stop us from going insane? Such a thin line we tread ‘tween contrary wise and unwise contrary.
