“Similarly, when you see a character jumping from a 100 story building and landing without hurting a bone, then believe that this is an example of special effects.   Special effects are provided by a few companies that use specialized software to add these effects. Many of these companies are located in India, in Bangalore and Mumbai. Movies like Avatar, Jurassic Park, and many others were sent to India for providing special effects.   Similarly, in Thor, when the main character rotates his hammer and generates a tornado, be rest assured that this is only an example of special effects. In reality, nothing like this happens.   And if you are able to do it, you are a superhuman, like Superman. You have got super-powers to do whatever you want and you can generate such a tornado by rotating your hand, even without a hammer.   So, my sincere advice to you is not to even attempt this. You will end up with a torn muscle, or a fractured hand, or maybe you may even suffer a heart malfunction and eventual death.   Let me not get into the science behind how this happens, but if you are educated enough, you will heed my advice and not attempt this anytime in your life.”
