Air Mortar
An air mortar (or debris mortar) is a device used to create movie special effects, consisting of pressurized air or gas forced through a tube to propel material (dirt, glass, fake blood) to create a bursting or splattering effect. A cinema journal from 1941 describes the air mortar as "inaugurated" in the film ''Caught in the Draft'': "this new development utilizes air blown under pressure through pipes, as well as powder and pyrotechnics, to gain unusual effects." Other debris mortars may employ black powder 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, carbon (in the form of charcoal) and potassium nitrate (saltpeter). Th ... to launch heavy objects. References Special effects Mortars {{film-tech-stub ...

Special Effects
Special effects (often abbreviated as SFX, F/X or simply FX) are illusions or visual tricks used in the theatre, film, television, video game, amusement park and simulator industries to simulate the imagined events in a story or virtual world. Special effects are traditionally divided into the categories of mechanical effects and optical effects. With the emergence of digital film-making a distinction between special effects and visual effects has grown, with the latter referring to digital post-production and optical effects, while "special effects" refers to mechanical effects. Mechanical effects (also called practical or physical effects) are usually accomplished during the live-action shooting. This includes the use of mechanized props, scenery, scale models, animatronics, pyrotechnics and atmospheric effects: creating physical wind, rain, fog, snow, clouds, making a car appear to drive by itself and blowing up a building, etc. Mechanical effects are also often inco ...

Fake Blood
Theatrical blood, stage blood or fake blood is anything used as a substitute for blood in a theatrical or cinematic performance. For example, in the special effects industry, when a director needs to simulate an actor being shot or cut, a wide variety of chemicals and natural products can be used. The most common is red food coloring, often inside small balloons coupled with explosive devices called squibs. Origins Alfred Hitchcock used Bosco Chocolate Syrup as fake blood in his 1960 thriller '' Psycho''. Since the film was in black and white, the color was less important than the consistency. Reasons for use There are many reasons for substituting for real blood in the film industry, such as ethical and sanitary concerns, and concerns for the emotional well being of the actors. Also, actual blood's tendency to coagulate and solidify quickly make it unsuitable for repeated takes without freshening; the longer-lasting viscosity of stage blood makes it far easier to work with on ...

Caught In The Draft
''Caught in the Draft'' is a 1941 comedy/war film with Bob Hope directed by David Butler. Plot Famous Hollywood actor Don Bolton (Hope) is a vain movie star whose biggest fear is to be drafted into the US Army. He definitely lacks the qualities of a good soldier; he is so terrified of loud noise, he cannot cope with hearing a single 'gunshot' when he is on set shooting a war film. There is great doubt that he could last even a day in the service. Colonel Peter Fairbanks (Clarence Kolb) visits the studio set as a consultant for the war film, and with him he has brought his beautiful daughter Antoinette, known as "Tony" (Dorothy Lamour). Don is smitten by Tony, and also realizes that his ticket out of the Army is to marry the colonel's daughter to avoid the draft. Don manages to gravely insult the colonel when he mistakes him for an actor and treats him disrespectfully. Even so, Don manages to go on a date with Tony, and even proposes to her before hearing on the radio that the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Powder
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, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon 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 and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
