There are powerful sleight-heavy effects, but the sleights for this effect are "so easy even a child
can do 'em." The DVD instruction is very clear.
What's not so easy?
*** Timing
*** Misdirection or as Eric calls it, "re-direction."
If your timing is off even by a
nanosecond, you will not be able to do this effect; you will make it a trick without much magic.
This will prove true even for finger flickers extraordinaire.
The effect also requires
powerful, but subtle misdirection.
This is a beautiful, elegant effect.
