What is the secret to the magic trick exile and x finger?
I don’t own the trick, nor have I ever seen it performed until just now, but after reading the description of the trick and seeing the video, I can tell you that it can be done (and probably was) with a pen containing thermal-reactive ink (for the dissapearing X’s) and regular (wet) ink for the ones that appear underneath the coin (Watch the magicians hand/handling of the spectator’s hand and coin in any you-tube videos demonstrating the trick) The pen that I believe is used can be purchased at any magic dealer under the name “SympathetInk” by the same guy who created this trick (Matthieu Bich)
