This is a packet trick revision of a trick called Ghost Cards. The following video has me do the trick as written in the instructions, followed by me trying to improve it.
The main problem with the trick as written is that there’s a lot of props and procedure to make one side of one card appear. In my revised version you can make four faces appear, which makes much more sense than just one. While not in the video, you can reverse the procedure to make the cards disappear at the end.
This is a trick that snuck into my close up set at the fair I recorded the video at. I forgot to take it out of my pocket the first day, and it lived there all week and I did it all week. It was fun, and I did it for people who had seen me multiple times as something different for them, but it’s not making it into the regular set.
