A practical effect is a special effect produced physically, without computer-generated imagery or other post production techniques. In some contexts, "special effect" is used as a synonym of "practical effect", in contrast to " visual effects " which are created in post-production through photographic manipulation or computer generation. Many of the staples of action movies are practical effects. Gunfire, bullet wounds, rain, wind, fire, and explosions can all be produced on a movie set by someone skilled in practical effects.
Non-human characters and creatures produced with make-up, prosthetics, masks, and puppets — in contrast to computer-generated images — are also examples of practical effects.

You're almost done. Connect to your existing Cracked account if you have one or create a new Cracked username. We mean no disrespect to the digital effects artists working in Hollywood, but sometimes it feels like computer-generated CG effects haven't improved in 10 years.
Every blockbuster seems to have at least one big effects scene that looks like it was lifted from a PS3. So maybe we need to stop and appreciate the mind-blowing scenes that were done the old-fashioned way -- with stunts, models and borderline insanity. Note: The mark of a good movie is that you get so caught up in what's going on, that you never even remember to think, "How did they do that? And that's what this Cracked Classic is all about: reminding you that no matter where you come from, no matter what you do, and no matter who you are, people who work on movies are better than freaking all of us.
It was a chase that destroyed the Batmobile, a Joker-themed semi, a dump truck, a paddy wagon, multiple cop cars and God knows how many bystander vehicles. And that shit was worth it. Batman on a motorcycle.
Burning, Bleeding, Floating, and Flying: Simple, Low-cost Special Effects
This should win Best Picture every year. Two specific points during the insane car chase at the halfway point of The Dark Knight are so over-the-top they seem like they would have had to be computer-generated, if for no other reason than they would have killed the stunt drivers. The scene ended up in the trailer and inadvertently encouraged a bloat of fanboys to flock to their keyboards and pound out protests against the fake-looking CGI in the movie.
But as Christopher Nolan has proved time and again, he doesn't mess with that shit if he doesn't have to. No, what you are actually seeing there is a complete one-third-scale model of the Batmobile, the garbage truck and a large section of lower Wacker Drive in Chicago.
Even the damn degree move that the Batmobile pulls off at the end was done by a radio-controlled model. So what about the climactic moment in that scene when they flip the Joker's wheeler after Batman clotheslines it with a grappling hook?
If that was a model, it was pretty goddamned convincing. The flipping of the semi was accomplished with a technique known in Hollywood as flipping a real goddamned semi. To get the mind-boggling amount of upward force needed to lift the big bastard head over heels, the FX crew built a huge steam-piston mechanism in the trailer.
Wait, why can't that shit come standard in cars now? Of course, then the challenge was to make it look like this insane stunt was occurring right in the middle of the banking district in Gotham.
So how the hell do you pull that off? Build a miniature city and edit in the truck somehow? Film the truck out on an open course and use CGI to fill in the background? Shit, no! They just went to downtown Chicago, closed off a street and flipped their goddamned semi.Carburetors and paint guns function according to the Venturi effect.
But, how does the Venturi effect work, do you wonder? Hang on, as ScienceStruck answers this question, along with explaining the applications of the Venturi effect.
Because wind blowing at a high speed creates low pressure, the air inside the house rushes out to occupy this void. Fluids are substances that have the ability to flow and undergo changes in their shape when subjected to stress.
They include gases, liquids, and even some plastic solids. Needless to say, owing to their ability to flow from one place to another, and their non-rigid nature, the study of fluid properties has always been more challenging than rigid solids.
However, it is this very fluid nature, and deformability, that has made many great advances in science possible. The pumping of water and oil, their transport by piping, the development of the internal combustion engine, and even modern aviation technology, all owe their existence in some way to the exploitation of fluid properties.
Thanks to their ability to flow, fluids can be transported through pipes and channels. In such kind of transport, pressure plays a very important role.
With the modification of pressure, fluids can not only be moved from place to place, but can even be exploited to do some work for us.
It was the Italian physicist Giovanni Venturi who discovered way back inthat even altering the diameter of a pipe can have an effect on the pressure of the fluid flowing through it.
Let us learn more about this concept, which was aptly named the Venturi effect. When a fluid moving through a pipe faces a constriction, or narrowing of the pipe, the velocity of flow increases at the constriction, with a corresponding drop in the static pressure.
This principle is called the Venturi effect. This means that, when the velocity of the fluid increases, its pressure will decrease. When a fluid flowing through a pipe encounters a constriction, it means the surface area at that point has decreased, resulting in a smaller opening.
So, to maintain the same rate of flow, the fluid molecules have to rush out at a faster speed through the constriction, to cover the same distance in the same time. This results in an increase in the speed of flow. The formula for kinetic energy of the fluid is:. Obviously, as the velocity of the fluid increases at the constriction, its kinetic energy will also increase.
This means that the total energy has to remain constant.We provide the video making community with thousands of free professional-grade production resources, and also distribute exclusive content that is the most affordably priced in the industry.
