Who else has witnessed?

i have seen this once before. but the man that showed me started a bond fire with it and he later explained it was his chakra that he (with many years of practice) controlled and willed it to happen. if that helps any

I have personally known a few professional stage magicians (no one big), part of the business is misdirection, they direct your attention to where nothing is happening, if they tell you to check their sleeves then there's usually not going to be anything going on there (unless they're really bad at it). If you know what your doing, you can use a person's own expectations to fool them, for example by wearing sparse clothing like a tank top most people would think it to be difficult to conceal anything, but using that misconception is what illusionist do best. Just don't get it mixed up with real magick, illusionist are there to entertain like TV, but all it is is skilled manipulation of your perception using basic psychology, props, and a lot of skill (though there are simple trick that anyone can learn, most of the big stuff and some of the small stuff require a lot of practice to pull off without making mistakes or giving the trick away, and some of the big tricks can be very dangerous if you make a mistake)

I find it moderately disturbing that this discussion needs to be had. Indeed, I thought we as a society (the world in general) had evolved somewhat beyond believing that stage tricks were real.

Ah well.

That being the case, I've got snake oil, land, a bridge... whatever you believe to be most valuable.
