I am not sure what others do wrong. I have very much success with this trick.
I fooled also a
lot of professional magicians with it.
Sure, you can use different (improved?) techniques to
perform it. A good alternative may be a PK Ring .
But the effect is unbeatable and definitely
something new and different.
I have done it with jeans at a party and in very formal environment
like galas, receptions (even much stronger) - heal an accident.
You can do it slow and very
magical (also with smoke, salt ...) or as a quick high speed effect. Lot of fun which "assistance"
of spectators.
I give in that it is a bit of "dirty" work to produce the prop, but it is
definitely worth to do it.
