I was playing around with the Erdnase color change, and I realized that I had accidentally pulled out four cards. I then set up four aces on the bottom, and was able to do the color change, but move four cards instead of just one. I am guessing people have stumbled across this before, but I looked on the internet and haven't been able to find a multiple card color change. I was really hoping this is original, as it would be so awesome to see magicians use my method as a basis for their tricks . I would upload a video, but I cannot find my video camera. If anyone finds something out there similar to it, could you give me a link to it so I can see if it uses the same method? Thank you!
