Holograms on chocolate





DIY process to copy commercial holograms onto chocolate! Completely edible -- no dyes or inks used. Tech Ingredients' video: https://www.youtube.com/watch?v=SoTi0tM4yQ8 Samy Kamkar's diffractive chocolate: https://twitter.com/samykamkar/status/1259173832620830722 Hologram stickers: https://www.ebay.com/itm/100-Huge-1-9-16-Round-Adhesive-Hologram-Sticker-Labels/331178956157 Silver mirror process: https://sci-hub.tw/https://doi.org/10.1080/00202967.1941.11869396 Add a pinch of sodium lauryl sulfate to the stannous chloride primer solution to help the solution get into contact with the plastic surface. https://www.youtube.com/watch?v=y-4qqcCxD6g Morphotonix: https://www.npr.org/sections/thesalt/2014/06/14/321816570/holographic-chocolates-look-as-beautiful-as-they-taste http://www.morphotonix.com/products/ Caswell nickel electroplating kit: https://www.caswellplating.com/electroplating-anodizing/nickel-plating-kits/nickel-electroplating-kit-1-5-gal.html (Price was already pretty high years ago, and has gone up a lot since; and the kit has fewer components than it used to. But it does work well.) Holography Marketplace book -- lots of very practical information for making your own holograms, and good source of suppliers (though many are out-of-business now): https://www.amazon.com/Holography-MarketPlace-6th-Franz-Ross/dp/0894960997 Very good source for mold making supplies: https://shop.smooth-on.com/ Countermeasures against hologram copying. Holograms are often used as a security seal, so making copies as shown in the video could be a problem without countermeasures: http://www.nli-ltd.com/publications/countermeasures.php I was planning to talk more about different types of holograms in technical detail, but I think I will save it for a future, dedicated video on making original holograms. https://www.patreon.com/AppliedScience
