He begins by demonstrating how to sprinkle powder on the skis that are placed on a large red table in front of him.  He spreads the powder evenly on the gliding surface of the skis.  Then uses an iron to go over the powered surface to heat it slightly.  Then he shows how the skis look after the powder treatment.
