Touch Tone by Matt Mello
"There's no way they'll figure out how you're doing this." -Matt Mello
Close your eyes to amplify your other senses and SEE COLOR using only your sense of TOUCH.
Here's what happens:
1. Your spectator can shuffle a deck of cards any way they like.
2. And yet with your sense of touch alone, you can tell whether the bottom card is red or black.
3. Again, they can shuffle. They can even inspect the cards carefully for marks, bumps, etc. They'll find nothing.
4. Once again, closing your eyes to amplify your sense of touch, you can tell whether the next card is red or black.
This is a secret that can easily be used in other tricks discretely, without making a show of it to identify chosen cards, 4 of-a-kind or more.
