Magic Tricks

I liked it. When I saw the seminar, I remembered that I had a similar trick and I showed it a very long time ago. I made the card myself. The principle is the same, but my card was made a little differently. It was thicker (of two cards), and the needle protruded when a small drawing on the map was displaced. I recommend this workshop. I think that this trick is best shown not as a separate trick, but in combination with other tricks. What would it be perceived as by the way.
