This mirage functions in a way similar to the previously examined paper craft illusions. Both the dragon illusions and the hex nut illusions use a concave formation to create a convex deception. The impossible shape allowing linear objects to pass through appear three dimensional to the eye but is actually not.
The printable model of this optical trick is unfortunately unavailable on the web it seems. People have recreated this paper craft trick by mimicking the exact model in the videos. I will be seeking a printable version with instructions for anyone that is interested in trying out this trick for themselves.
The crazy nuts optical illusion was first devised and demonstrated by the late Jerry Andrus. Jerry Andrus, a prestigious illusionist, developed numerous optical tricks throughout his career. He was featured on Bill Nye the Science Guy with the hex nut trick being just one of his many creations.
