Revamped for 2015! A simple effect, but one that will have them going crazy.  One of the things that I deal with when I receive magic from Thomas is there are no instructions until later and so I'm forced to look at a prop and figure it out.  When I received the Da Vinci Box the other day I had no clue how to open it, but even with this seemingly innocent and simple block I also had no clue.  Both times Thomas had to explain how. This item may not be as impressive as some of Thomas' others, but it is more likely to find its way into your performing repertoire - it is easy to do and a fooler too!
