I am aware of that effect, and I have seen it in action. I am trying to reconcile what I see in the video with what I have seen of Leidenfrost in the past.

He actually grips the object, and I don't see extra smoke. When I have observed the Leidenfrost effect in the past, I see a noticable increase in outgassing, and the liquid (as it usually is) skitters about freely, so it seems like it might be difficult to grasp an object through the vapor layer.
