Accidentally stumbled on this video on the Internet, you might not to notice, but if you watched the attention, it should be noticed that the blades of the helicopter did not move, although he is in the air. So how is this possible?
From the outside, it seems that some magical force causes the helicopter to hover in the air. But this optical illusion effect is made possible due to the coincidence by which the speed of rotation of the blades coincides with the frame rate of the camera. The result seems to be that the blades are not moving. However, when the plane starts moving forward the rotation speed of the blades increases, and in the video you can see how they slowly begin to move.
