Hello,
I need a magic trick to write on some deck cards with an invisible ink.
I need to write with my index finger on the cards, no one should be able to see that i'm writing with some invisible ink.
I need you to be creative ! Do not hesitate to ask as many questions as needed.
Best of luck !
I can give you some ideas.
