Wow, I’m so glad I live in the 21st century. Sure, we might not have hover cars yet, but at least the world finally has chocolate etched with rainbow holograms!
The holograms weren’t made using any sort of added chemicals—they were actually created using a unique etching process that was developed by a Swiss design company, Morphotonix, and a German chocolate mould manufacturer.
Basically, the holograms are made by carving detailed microstructures onto a metal master mould, which is then used to make softer plastic moulds. Chocolate is poured into those plastic moulds, and the resulting etches carve specific microstructures that can defract light (security holograms on credit cards work in a similar fashion).
The process works with both milk and dark chocolate. Morphotonix began developing the hologram tech back in 2012, but there isn’t any word on when these chocolates or the moulds will be made available to the public.
