Card Melt-Free Magic Trick
If you watch the video, you will see how to cut the card correctly and where to stick the cut card. It is a very easy gimmick to create and use. Watch the video to see it being made.
Use a sharp pair of scissors to cut the bottom of the card and try to keep it in line with the pattern of the card.. this way it is hidden well in front of a spectator.
One thing I will add is try to use a deck with a good design on the back of the cards.. It makes it easier to disguise the gimmick. Use your thumb too to hide the corner.
As you watch the video keep an eye on what the person’s hands do. Once you have created the gimmicked card it is yours for life.
