Safety fuse

                                                         In the 10th century,
                                              the Chinese developed a fuse to
                                              delay the ignition of gunpowder.
                                              An English leather tanner named
                                          William Bickford went one better and
                                       invented the modern safety fuse in 1831.
                                          After watching a friend make rope, he
                                           wrapped a core of gunpowder inside
                                        a twist of string and, voilà!—the modern
                                       fuse was born, enabling miners to set off
                                               explosives from a safe distance.
                                                          Phews all around.

                                                                  Dynamite discovery

                                                        Italian chemist Ascanio Sobrero discovered
                                                    the highly unstable liquid explosive nitroglycerin
                                                             in 1847. Then, in the 1860s, Swedish
                                                   entrepreneur Alfred Nobel mixed the more stable
                                                     solid nitroglycerin with sodium carbonate and
                                                     a shock-absorbing powder to make dynamite.
                                                    The creator of this weapon of mass destruction
                                                         gave his name to the Nobel Peace Prize.

                                                 Dynamite, usually sold in paper-wrapped sticks, was a smash hit in industry. It
                                                 was used to mine important materials such as steel, copper, silver, and gold,
                                               and the transportation system, from roads to tunnels, was built by blasting
                                               away rock with dynamite. Other large-scale construction projects, from
                                                         dams to canals, also relied on its useful obliterating
                                                                             capabilities, as well as the
                                                                               precious South African
                                                                                   diamond mines.

                                                       TNT
                                            In 1863, German scientist Joseph Wilbrand
                                             discovered TNT (trinitrotoluene)—a yellow
                                            chemical explosive that is more stable than
                                         dynamite. TNT can be melted down and poured into
                                         shell casings, making it valuable in weapon making,
                                           although its yellowness rubs off on anyone who
                                          handles it; workers who used TNT in World War I
                                          weapon factories were nicknamed “canaries,” as
                                            the chemical turned their skin bright yellow.
