Anyways without exposing the secret, the basic idea of MindShades is allowing you to gain secret information in a clever way. For instance, if you do the classic trick with the block of wood and the peg, and you narow it down t wich one it is by slamming your hand down on the styrofome cup, you can do that impromtu at a moments notice.
You can use it to see what card a person picked or see what part of a wall someone touched.
The prop comes with a little booklet that includes 8 different routines. Hope this helps. If you like mentalism, you'll like this trick. If you like "Street trick" then you like this. If you like magic that can be done at a moments notice, then you will definetely like this!
Hope this helps!
