ok watched the entire thing, cursorily.
well, it's just plain stupid.
there's no Chi involved what so ever. Basically, what he does is put one hand up, and then focus you to other things, like that tong thingy that has nothing to do with anything. The hand then
NATURALLY,
without any other intervention, stretches and changes in size.
In the same manner you can increase the length of you entire arm by flexing it in and out (like
this(click!)).
Also, you change the color of your hand by putting one arm above your head and the letting the other loose beside your body. After some time the one above the head will be red and the other one will be white. That's how you can get Red Hands >=D
Also, you can see this if you grab someones arm really tight (just below the hand joint). In that manner, you will disrupt\stop blood supply to the hand. The grabbing needs to be seem as a casual thing, as if you are just getting a good grip to do it right. Then you do some 'magic': you move some (of the other person's) fingers around and touch spots as if you were doing something important, changing the chi flow, and basically, anything goes here. After a long enough duration of time passes, lift your hand as if riding hot air coming up, and at the same time, release your iron grip. The release lets blood rush in again, and causes a certain sensation of filling, and with the other hand rising up, it seems to be a wave of energy passing between the hands.
And so forth and so forth.
