The effect has been around forever!
Well, at least a really long time ;-)
So, as the ad states
"...This is NOT the standard handling of the Hindu Thread as detailed and repackaged by so many other performers. It has been re-thought and re-designed to maximize the impact while ensuring that the effect is completely foolproof."
There you go!
What is the value, to you, to have a trick vs. having a special act?
