How to learn maps by touching them lightly
 

To execute this focus, you must prepare the cards in advance. Take cards with shapes and a sharp knife or a blade, swipe the edges from left to right. As a result, it turns out that you stabbed the edge of the map with a knife and made a strip on each side of it that you can feel with your hands and which you can not see with your eyes. Next, take the cards over your head and touch them one at a time, tell the audience whether the card is a card or not. You can even blindfold the map. During the performance of the focus, the viewer should not see that you are feeling the map. The movements of your fingers should be nimble or slippery. It is recommended that this focus be shown after focus, which is based on mathematical calculation.
