In having purchased your effect Asmadi....
Your ad copy is actually
correct, I will confirm.
Yet, whilst your method which you previously
advised was unique, I would firmly state it is so unique only because it is simply not practical as
a workable method a magician can use to perform this effect on a regular basis, or even more than
once when the arts & crafts are done to be totally honest. The set-up, time and physical work
involved to only be able to perform this effect once each time is sincerely impractical.
This is not a "worker" effect, which magicians can depend upon and perform multiple times each
time they're performing somewhere, and continue to perform any time they wish to do so. Not unless
they are prepared to spend many, many lengthy hours preparing the necessary elements completely and
totally for each singular and specific time they wish to perform this effect.
As a "one-off" effect a magician may choose to perform for someone special, it indeed has
strength. But as a "real" world "worker", this concept appears to have been completely "rushed" to
market, and therefore its overall strength as an effect, specifically in regards to its viability in
being performed regularly by any magician who purchases it is severely lacking.
