Invisible Lie Detector by Wayne Dobson & Alan Wong

The Invisible Lie Detector is the latest in Wayne Dobson's output of quick, powerful, simple close-up mental routines.

Eight cards bearing the names of everyday objects.
One is freely chosen under the fairest conditions
Byplay involving an 'Invisible lie Detector' and the spectator lying about his or her chosen object to try and put you off the scent.
The performer has the matching object in his closed hand
Super-simple and a lot of fun to perform
Each time the choice can be of a different object
Uses everyday objects and they are included
Resets in an instant
Provided with everything you need to perform it, straight out of the box!

Puts a smile on your face every time you perform it: Wayne's method is every bit as good as the effect!
