Attention!

Due to special experimental conditions, video filming could only be made in the presented shooting position.

For light portable and mobile devices (laptops, tablets, smartphones, etc.), it is enough to launch a video for viewing at the link below and rotate the screen of your device so that the movement of the object is seen vertically up and down.

To watch a video on a stationary computer with the ability to rotate the image, you need to install on your PC the lightweight and free VLC media player program, version 2.2.1 and higher (18.6 mb).
