I've included a full description with pictures on how to do this. I know you guys don't like videos, but it's kind of hard to follow without seeing it done, so I made a video of it as well:
Check out the next steps for the explanation. Have fun with this!
Step 1: What Will Happen
If you didn't watch the video, this is how it will look. You place a coin on the table. Next, you will cover it with your hand and rub it in circles. After a few seconds, you will lift up your hand and show that you've rubbed the coin out of existence!!!
