Can someone explain the science behind this process? It looks really cool but I don't understand how this is achieved. He puts the chocolate into a vacuum chamber and molds it with something? Or is it the vacuum itself that adds the effect without the chocolate being merged with anything?
- kd5bjo 6y agoDiffraction gratings are composed of a series of ridges spaced very closely and regularly, and this physical shape is transferred to the chocolate through the molding process. Light bouncing off of the different ridges creates an interference pattern which varies for different wavelengths of light, creating a rainbow effect. https://en.m.wikipedia.org/wiki/Diffraction_grating https://en.m.wikipedia.org/wiki/Diffraction_grating
- heftig 6y agoGoogle for a "reflective diffraction grating". If you shape the surface a certain way - grooves with a size near the visible wavelength, AFAI understand - you can get the reflected light to interfere with itself. The imperfections which vary the groove size then result in this rainbow effect.
