Thanks to Physics, This Chocolate Is Iridescentand Safe to Eat –

Those familiar with chocolate will recognize it in many flavors, from milk to extra dark, and in many forms, from syrup to bunny. But recently, Samy Kamkar debuted his take on this age-old treat: iridescent chocolate that glimmers like a rainbow.

The shimmery sweet looks like something out of Willy Wonkas universebut this one comes with no side effects, as Devi Lockwood reports for the New York Times. Its surface has lots of miniscule grooves that diffract light like a prism, giving the chocolates surface that mesmerizing sheen, Kamkar explains.

Kamkar founded the internet security company Openpath and likes to tinker with his food in his spare time, he says. Anyone can do this at home, he tells the Times. Theres no coating. Theres no special ingredient. Its the surface texture of the chocolate itself thats producing it.

Anyone who has a 3-D printer, that is. To make the chocolate, Kamkar created a mushroom-shaped mold with multiple ridges micrometers apart. He tempered the chocolate, poured it into the mold and then put it in a vacuum chamber to prevent air bubbles on the surface. (He chose a mushroom shape because theyre magical, he tells the Times.)

As Marnie Shure reports for the Takeout, Kamkar posted a video of his creation to Twitter on May 9, where users were fascinated with his success.

As Renusha Indralingam explained in Yale Scientific in 2013, iridescence occurs when an objects physical structure causes light waves to combine with one another, a phenomenon known as interference. In the natural world, hummingbirds, beetles, butterflies, peacocks and many other living organisms exhibit iridescent traits, which they can use to choose and attract mates or evade predators, Indralingam wrote.

Kamkars idea isnt new. In December, researchers at ETH Zurich and the University of Applied Sciences and Arts Northwestern Switzerland announced that they had filed a patent for the process of making shimmery, iridescent chocolate without additives, per a statement. The scientists said they were in talks with major chocolate producers about scaling up their discovery for commercial use.

Patrick Rhs, a scientist involved in that project, tells the Times that one of the biggest problems they face will be convincing consumers that the chocolate is safe to eat, reflective surface and all. Maybe the surface is actually too shiny. [] People think that there is a plastic foil on top, which is not the case, he says.
