Impossibble Helicopter - Tricky

This is a very fascinating science involved in this matter. This video shows that the rotor blade of the helicopter seems doensn't move at all.... Is it really?? Take a look first.




The science is simple;

The rotor blade spinning at the same rate of the video frame.

Eg : Spinning of the rotor = 2500 RPM (Round Per Minute)

Video frame capture = 2500 Frame Per minute

So what you see is almost fixed rotor blade without spinning. Remember, your eyes does not always tell you the right thing.
