Practice. The main, and most important ingredient to any magic trick. Even a simple thumb tip
requires practice, scripting, and thought, for it to be ever considered "A miracle".
Can
this be performed immediately, yes (agreed, that you do need to purchase 2 rubix cubes, but that is
minor considering the degree in engineering one needs to construct some of the other gimmicks sold).
That being addressed, with minimal (hours, not minutes) practice, you CAN achieve an
astonishing miracle. don't be fooled by the lazy other reviewers. If you punt in the effort, it will
reap the rewards. I have spoken with the creators, practiced the routine, and delivered nothing sort
of the impossible. You will as well...
...unless you are lazy and impatient.
