Magic Tricks

As I say in the title, I like the concept, the gimmick and other materials that come with the DVD. Jeff also teaches an extra trick with cards that is lovely (production of four aces).
However, having performed this effect for a number of friends and family, people are distinctly underwhelmed.
They do not see me doing any 'tricky' moves (so it is unlikely that the problem is about technique so much). Rather, they come to the only logical conclusion about how the trick must work- and are of course right!
Hmmmm...
I will continue to work on this one to see if I can find ways to be more fooling, as I do like the concept and materials.
