You need a detailed description of the mechanism and principles (for example, is it done with a particle system or not? Or is PhysX technology?)

Just please do not write "well, with the help of this or that, you need to do it" - I need preferably not only the principles of creation, but also concrete examples - links to text / video tutorials.
