What a brilliantly demonstrated principle presented in a clear simple way. I loved watching the stall develop from the root and trailing edge out to the tip and leading edge.
If you notice, as the wing begins to stall the separation begins toward the root of the wing and moves toward the wingtip. It also begins at the after part of the wing and moves forward. Great reference video!
like the discription says: it shows the airflow over the wing. in normal fligth conditions the threads on the wing stay on wing. but when the plane stalls and the angle of attack gets to big and the smooth airflow becomes a turbulent area of air. so you won't get any lift which makes the plane drop from the sky. the turbulent area can be seen by the woolen threads moving allvover the wing.
Actually, some gliders don't have retractible landing gear... I've flown one of these gliders, and it's one which can't retract the gear... The gliders that are used in competitions and go really fast, those are the ones that have retractible ones!
@anorup Thanks! That was indeed a surprise for me too!

Very good demonstration, and surprisingly dramatic. It looks like the airflow not only gets turbulent but actually reverses direction!

if you want to know the reasons for this effect of lift and moving vortex points research the magnus effect relating to newtons third law,
