explaining the concept of mechanics to him. I really like that because my brain works that way; I like to know the "why" and "how" of things.
Just a thought...make a 6-8 inch plastic snowboard out of a milk carton or something to show him torsional steering; fore/aft weighting during phases of the turn, de-cambering the snowboard and engaging the sidecuts for turns; and using the idea of keeping your body parts inside the cereal box (the board being the bottom of the cereal box) to show how that effects balance and efficency.
