He talks and demos with those possessing pung and those not. Another outlook might be that all have pung, relative to another.
Which means all can be interacted with depending on the sensitivity/timing of ones touch...pung "expanding" force is inherent
by the bodies reaction to the pressure of the air "Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch"

Chu and I do a little free push hands. Chu has pretty good pengjin now but hasn't yet got a great root, so I manage to displace him fairly easily and spectacularly. One of the girls wants to experience this but of course collapses rather than bounces. I explain why this is so and why pengjin is useful.
Finally, I use Taiji's Raise Hands movement to allow her to safely experience what pengjin feels like.
