And then there was the mix of a certain weedkiller (now outlawed) and sugar that formed a junior but potent version of thermite. With a length of guttering as a Fireball XL5 style launch pad, lightly modified plastic bottles, and my weedkiller/sugar mix, I was in the rocket business. Some of the rocket bottles flew a surprising distance; one certainly surprised me by shooting about a hundred feet into the air in a graceful arc that carried it over the brook into a trash pile in the yard of the blast furnace. Like Wernher von Braun, I had aimed for the stars, but hit a civilian target instead. Luckily the small fire that the burning rocket bottle started went out before I had to wade across the brook to deal with it. Even more luckily, I still have all my fingers and thumbs; the only souvenir of my rocketry experiments is a small oval scar at the base of my right thumb.
