An illusion you can eat: YouTuber and baker CharlotteSometimes created a mesmerizing frosting design that appears to shift colors depending on the angle of the viewer. The wavy design look yellow, orange, and red from one side but green, blue, and purple from another.

How did CharlotteSometimes work her magic? With the help of an airbrush tool and a unique frosting technique. In the tutorial, the baker explains that she painted one side of the frosting with warm colors and the other with cool colors. Thanks to the ridges, you can only see one side of the frosting and therefore only one color at a time. As you spin the sheet cake, the colors blend into each other to create the illusion.
