From Youtuber and illusion-maker extraordinaire Brusspup:

Below are links to the images found in this video so you can print them out and try it yourself. You’ll have to print the template onto a transparency. If you have an ink jet printer you have to use a special transparency made specifically for ink jet printers. When you print the images and the template make sure to print them all at the same size

if any of the sizes change the effect will not work.
