It is difficult to imagine a Hollywood blockbuster without special effects. Incredible visual tricks makes our favorite films even more spectacular and interesting to see. But some action scenes actually seem to defy the laws of physics for the sake of art.
Great.guru leaves you with this list of fun special effects genius in popular movies that should carry the warning “don’t try this at home”.
9. The vehicles can fly
It seems that filmmakers love to make that cars and buses fly as if there were no gravity in this world. The bus jumping over bridges incomplete, and the cars fly after it hit. We are sure that you have seen these scenes in your blockbuster favorites. However, the laws of physics cannot be ignored so easily.
In real life an object such as a car or a bus would jump over a gap or I would fly off after a crash. The explanation lies in the kinematics of projectile motion, which says that no matter how fast you travel an object, if it is launched horizontally, it will always fall.
8. The sound and light travel at the same speed
Every time we see a ray in a film, we hear the sound of a lightning bolt. Occur simultaneously. However, each student knows that the light is more rapid. Just more proof that we should not learn physics of Hollywood movies.
In real life first you see the lightning and then you hear the sound. The speed of light is 299.792.458 meters per second. The speed of sound is only 300 metres per second, depending on the temperature, the density of the air, and many other factors.
7. The lasers are visible in all parts
Often used laser weapons for space battles, isn’t it?. However, the appearance of a laser beam as a ray of light, especially in space, is just another myth of the big screen.
In real life lasers would not have any possibility of shine. When a laser beam becomes visible, it is dispersing small particles that are lost to over his career. The visibility and the color of the laser beams only depend on the means by which they travel, which contain dust particles and air molecules. And we know that there is no air in space.
6. The explosions of vehicles are imminent
It seems that even the smallest damage to a vehicle in a movie is a great explosion, no matter if the car simply fell off a cliff, or if two vehicles collided with each other. Shoot a tank of gas left a small dent and, boom!. An explosion terrible turns the car in a burst of flames. Do not take this for granted.
In real life the vehicles rarely catch fire when they crash. Gasoline is a liquid and the gas is burned as a vapor. Therefore, the liquid gas in a tank would have to become vapor, mix with air in proper proportions and ignited, so that the car explodes.
5. The bullets travel at the same speed in the water
Those scenes where people are immersed in a body of water such as a pond, a channel, or even an ocean to avoid being hit by a stray bullet are endless. Even so, there is a great mystery about whether being under the water can save you from the bullets.
In real life the bullets generally do not go beyond a few centimeters into the water. An opposite force or the resistance of a fluid against the motion of an object (called a drag), it opposes the forward motion of a bullet. The projectile sail with enough ease through the air, but as soon as it reaches the surface of the water, things change.
4. The guys great do not look at the explosions
The explosions are epic, which destroy buildings and cars are a special effect very popular in the movies. And most of the times, if there’s an explosion, there is also a hard guy not to look, but walks away with determination. This is not how it works in reality.
In real life the shockwave would kill the hero. The energy released in an explosion creates a shock wave, supersonic strong enough to knock down a huge building and, yes, a human being also.
3. The sounds can be heard in outer space
Filmmakers often “added” sounds to their scenes in space. If you’re trying to remember a scene in which a spaceship chasing a villain in a distant galaxy, you’ll hear the sound of shooting guns, launching missiles and roars of the engines. Well, again, this is just to give us an extra dose of emotions and a spectacular action scene on the screen.
In real life no one can hear sounds in outer space. What we call “sound” are really vibrations in the air. And as there is no air in space, there is no sound to the outside. As it says in the tagline of Alien: in space no one can hear you scream!
2. The radioactivity makes one shine
The science fiction and films make people believe that radioactivity is contagious. A hero who was exposed to the radioactivity becomes shining in the darkness and all the other avoid touching it. But that is not exactly what happens.
In real life most of the radioactive elements are not contagious. Radioactivity is the explosion of the core which damages the DNA. Other atoms that do not become radioactive.
1. Jump through a broken window is no big deal
Who doesn’t like those dramatic moments in Hollywood movies when people escape shattering glass windows and running for their lives? And without a scratch! But that is only a trick that you should never try at home.
In real life, a window shattered contains thousands of edges are incredibly sharp and points in the form of a dagger. Almost do not need strength for these points or edges to cut fabric and the skin, assuming that the glass fragments created by breakage to last longer, and that the force of resistance was sufficient. Even so would make mortal wounds to anyone that is moving through the glass.
When you watch a movie, all we’ve ever shouted at the screen: “Come on already! How is that possible?”. Then, if you did, share with us your favorite scene of special effects that seems to be mocking the physical.
