our bodies produce all kinds of energy, from electromagnetic fields to actual light. Yes, we
glow softly.
However, some of the tricks I saw on this video, I've seen before, such as "spirits" in the kris making it move.

This is a random youtube video, but I used to do this same trick myself in high school. Balance a long object such a pencil, or a kris, on it's balance point, and it's very easy to make it move with an undetectable puff of breath.

So, if this one thing is likely a trick, it paints a shadow across all of the other effects shown in the video, I think.
