"Nital is a solution of nitric acid and alcohol commonly used for etching of metals. It is especially suitable for revealing the microstructure of carbon steels. The alcohol can be methanol, ethanol or methylated spirits.
"Mixtures of ethanol and nitric acid are potentially explosive. This commonly occurs by gas evolution, although ethyl nitrate can also be formed. Methanol is not liable to explosion but it is toxic.
"A solution of ethanol and nitric acid will become explosive if the concentration of nitric acid reaches over 10% (by weight). Solutions above 5% should not be stored in closed containers. Nitric acid will continue to act as an oxidant in dilute and cold conditions." --Wikipedia

Really now
Down tempo flying saucer hub cap analog drive across Canada in an old wagon of hope with wheel wells like Mars and loose tape distortion street beat bringing me back to younger days watching Rick Hansen on the CBC churning his wheels with outsize arms across the world and Terry Fox and Expo 86 and French Canadian Sesame Street and that guy - I don't who he was - who would take you to all his childhood neighbourhood haunts, empty playgrounds, clean sward and chain link, leap up on something very casually and very freely, and say this is where I used to play...etc. simple and seared in my mind. You will not capture Sasquatch on digital. Don't even try.
