I was a little intruigued by this trick. It is not a trick that is to be performed without any
other tricks at hand and it is really not something that can be performed in front of the same
person over and over again, so that would mean you would have to be careful of who is watching you.
I was able to figure it out by only watching the a video a few times before the crystal actually
arrived which means it is easy to figure it out once you have a lead. I gave it a 3 because I like
tricks that can be performed in front of someone for weeks and when they go home and do everything
to figure it out... they never can figure it out.
Besides that, I think this is a great trick to
buy as long as you have other great mentalism (or just great) magic trick ready for after this
one...but let me remind you DO NOT ATTEMPT TO PERFORM THIS TRICK ALONE. ALWAYS HAVE MORE TRICKS TO
ATTEMPT AFTER THIS ONE IS DONE. Also... NEVER PERFORM THIS TRICK TO THE SAME PERSON MORE THAN ONCE
OR TWICE! (You might spoil the magic in it :P )
