Wow, visible lifting-force physics! Jump right to it at t-4m43s The "Newtonian downwash" shed vortices produced by Bernoulli equation is directly visible.
Also the video shows the actual purpose of wintip winglets: they force the tip-vortices to attach to the very end of the wing. Without them, often the vortices will break loose and migrate many yards inwards, and the far part of the wing then starts contributing negative lift. (See military videos of smoke patterns in "flare angels" from C-130 missle defense flares. Often you can see that the tip-vortices aren't connecting anywhere near the wing tips.)
