Effect:
You start with a clear acrylic cube with 6 different color gem stones.  The magician rolls it between his fingers and it becomes a clear sphere withe the gem stones.  Then the magicians smacks it down and it is now a acrylic disc with the gem stones.  Comes complete with cube, ball, disc and a mini magic wand.
 
This is a fun and unique Close-Up effect that can be performed on a table or in the spectators hands!
