In New Zealand in the 1930s, farmers reportedly had trouble with exploding trousers as a result of attempts to control ragwort, an agricultural weed.〔("Trousers Explode ), Evening Post, 21 April 1933〕 Farmers had been spraying sodium chlorate, a government recommended weedkiller, onto the ragwort, and some of the spray had ended up on their clothes. Sodium chlorate is a strong oxidizing agent, and reacted with the organic fibres (i.e. the wool and the cotton) of the clothes. Reports had farmers' trousers variously smoldering and bursting into flame, particularly when exposed to heat or naked flames. One report had trousers that were hanging on a washing line starting to smoke. There were also several reports of trousers exploding while farmers were wearing them, causing severe burns. The history was written up by James Watson of Massey University in a widely reported article, "The Significance of Mr. Richard Buckley's Exploding Trousers",〔("The Significance of Mr. Richard Buckley's Exploding Trousers: Reflections on an Aspect of Technological Change in New Zealand Dairy Farming between the World Wars" ), Agricultural History magazine〕 and which later won him an Ig Nobel Prize〔(James Watson for "The Significance of Mr. Richard Buckley’s Exploding Trousers." ), improbable.com〕 ==On television== In their May 2006 "Exploding Pants" episode the popular U.S. television show ''MythBusters'' investigated the idea that trousers could explode based on the events of New Zealand in the 1930s. Experimenters tested four substances on 100% cotton overalls: * A paste comprising a mixture of gunpowder and water (since gunpowder by itself does not cling to clothing); * An (unnamed) "herbicide from the 1930s"; * An (unnamed) "fertilizer from the 1930s" (this was most likely ammonium nitrate, the bottle was in the foreground of the shot and the label was facing the camera); * "An acid", likely a nitric/sulfuric acid mixture, (to make nitrocellulose/guncotton). Each of these were put to four different ignition methods: flame, radiant heat, friction and impact. Although not naming "the herbicide" as sodium chlorate, they confirmed that trousers would indeed vigorously combust due to flame, radiant heat and impact, though their friction tests did not cause ignition. However, combustion (i.e. an exothermic chemical reaction between a fuel and an oxidant) is not the same as an explosion, which involves a rapid increase in volume accompanied by the release of energy in an extreme manner (i.e. a shock wave). Even so, a person witnessing such an event (especially if he or she were wearing the trousers) would likely describe such a sudden event as an explosion. The tests also revealed that none of the other three substances caused combustion of the trousers, thus indicating that sodium chlorate was probably a cause for the events that occurred. ABC's ''The Science Show'' described exploding trousers as "the scenario for a Goon Show", and, in an example of art imitating life, it actually was. The Goons wrote a script about a chemical which "when applied to the tail of a military soldier shirt, is tasteless, colourless, and odourless" but that "The moment the wearer sits down, the heat from his body causes the chemical to explode.".〔(【引用サイトリンク】title=Tales of Men's shirts )〕 In the final episode of ''Blackadder Goes Forth'', Captain Edmund Blackadder says that he's "Off to Hartlepool to buy a pair of exploding trousers" when feigning madness to avoid going over the top. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Exploding trousers」の詳細全文を読む スポンサード リンク
