Iridescent Chocolate: Edible Chocolate Diffraction Grating
Full details at https://samy.pl/irichoc/
I experimented with diffracting waves of sound and light and considered if food itself could be cast as a diffraction grating of visible light, and was finally successful with an easily manufacturable and repeatable process for producing edible, iridescent chocolate at home within vacuum.Additionally reported on in The New York Times and The Takeout.
I’m finally getting some decent results producing 100%-edible iridescent tempered chocolate. The colors are from the chocolate (not any ingredient or coating) diffracting light after being forcefully molded onto a diffraction grating in vacuum. pic.twitter.com/6wpbsIKh5C

After failures attempting lasing gratings, finally designed mold in @adskFusion360, laser cut acrylic plates (variable thickness) w/@glowforge, turned rods w/Grizzly G0765, CNCd diffraction grating w/@Inventables Carvey, tempered+pressure injected chocolate, pulled vacuum @ 4torr pic.twitter.com/pKsS1tuV7e
