As i have mentioned in the past, being very good friends with a couple of the world's best stage magicians definitely keeps me a bit skeptical of such displays. Seeing is not always believing.

Kai Wee's sodium explanation is just one example of how this could have been done to fool Pangeran and his friend.
Still, i do not completely dismiss that such things could occur. I also would not completely dismiss the "master" who i might catch at such trickery. A great deal of working magick effectively is the "show". Magick most often works through our states of mind and it is remarkable what the mind can manifest into reality through belief. Many wise "masters" therefore use trickery to put people into an accepting state of mind that will allow the "real" magick to occur. This is certainly not always the reasoning and unfortunately much trickery is merely used to seperate a "poor sucker" from their money.
In trying to reach judgement about such cases i alway ask myself, how much money is involved and just who stands to gain. I generally feel more secure about spiritual experiences which are not bought with money.
