Dynamite is an explosive made of nitroglycerin, sorbents, and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867. It rapidly gained wide-scale use as a more robust alternative to the traditional black powder explosives. It allows the use of nitroglycerine's favorable explosive properties while greatly reducing its risk of accidental detonation.
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, charcoal, and potassium nitrate (saltpeter). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines, tunnels, and roads.
Tom Swift Jr. is the central character in a series of 33 science fiction adventure novels for male adolescents, following in the tradition of the earlier Tom Swift ("Senior") novels. The series was titled The New Tom Swift Jr. Adventures. Unlike the Nancy Drew and Hardy Boys titles that were also products of the prolific Stratemeyer Syndicate, the original Tom Swift stories were not rewritten in the 1950s to modernize them. It was decided that the protagonist of the new series would be the son of the earlier Tom Swift and his wife, Mary Nestor Swift; the original hero continued as a series regular, as did his pal Ned Newton. The covers were created by illustrator J. Graham Kaye. Covers in the later half of the series were mostly by Charles Brey. A total of 33 volumes were eventually published.
John Henry is an American folk hero. An African American freedman, he is said to have worked as a "steel-driving man"—a man tasked with hammering a steel drill into a rock to make holes for explosives to blast the rock in constructing a railroad tunnel.
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. Tunnels are excavated through hard rock, wet or dry soil, or sand, each of which requires specialized technology.
Internal ballistics, a subfield of ballistics, is the study of the propulsion of a projectile.
Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder. The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products for black powder. In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the barrel.
Indiana Jones Adventure is an enhanced motion vehicle dark ride attraction based on the Indiana Jones film series, located at Disneyland and Tokyo DisneySea.

Milo is a chocolate-flavoured malted powder product produced by Nestlé, typically mixed with milk, hot water, or both, to produce a beverage. It was originally developed in Australia by Thomas Mayne (1901–1995) in 1934.
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.
Suitcase: Failed Experiments and Trashed Aircraft is a four-CD box set released by Guided by Voices in 2000.

The Baltimore Mine Tunnel disaster was an explosion that occurred on June 5, 1919 just inside the mouth of Baltimore Tunnel No. 2. The Delaware and Hudson Coal Company's mine employed 450 workers and was located in Wilkes-Barre, Pennsylvania, about a mile from the center of the city near the modern day corner of North Sherman, Spring, and Pine Streets. Ninety-two miners were killed and 44 injured in the explosion, which was caused by the ignition of black blasting powder. Only 7 miners escaped without injury.
