      @HUDZY its not that hard. take some food grade cacao/cocoa butter(make sure it's 100% food safe and edible do not use any cosmetic grade cocoa butter) powdered nonfat milk and powder sugar.(a good starting recipe would be 40g of cocoa butter 40g of nonfat dry milk powder and 20g of powdered/icing/confectioners sugar.) Melt the cocoa butter over a double boiler. once its melted add in the powder sugar until it's fully incorporated. Add the milk powder and stir till fully incorporated. You should probably refer back to Ann's how to temper chocolate video since she explains how to temper white chocolate since it's a lot harder than milk or dark. Although with this recipe i've had luck with just refrigerating it and it setting up just fine. White chocolate is a lot softer than all other chocolates just because its all cocoa butter which has a tendency to melt quick so depending on what you need it for you can chill it in the fridge or temper it. source: www.alphafoodie.com/how-to-make-white-chocolate/

    as someone who used to do a sport requiring me to use micron grade equipment pretty often, a 2 micron is smaller than my smallest grade of diamond polishing paste. for reference, said polishing paste was something we used to only use for races. it made our steels almost perfectly reflective, and if a 3 micron paste makes steel almost mirror-like, a two micron gap is pretty insane

    I just tried thid for the first time :) First attempt failed (I used the back of the diffraction grating...). Second attempt worked! I've just finished bouncing off the walls!!! I took some 50% dark chocolate, melted in the microwave until it was just starting to melt, then took it out and stirred until it had all melted. I spooned it onto my diffraction grating, then let it cool. Then... HOLO!!!!

    I made this and my family loved it! Thanks Ann! Only one odd thing happened when pulling it off the diffraction grating. some places pulled away from the grating more quickly than others, and those places looked a bit less shiny and formed some lines in the chocolate where the color was a bit different. Any idea as to if this is because of uneven cooling, tempering, etc?

    I've enjoyed your work for years, but it seems a pretty major oversight in research not to credit Tech Ingredients (the likely source) a mention for this. Their video on this came out in 2018, and I believe is the first on the subject showing how to do it at home. There's been a recent group of more "influencer-y" type duplicating their result only in the last few months. Especially given your advocacy against content plagiarism I'm kinda surprised you didn't at least mention that Morphotonix of Switzerland first invented the technique, or link to the Tech Ingredients video showing how to do it at home. Is this your own, original idea?

    Came here from Simply Nailogical's video because people in the comments said you had science haha. I thought I understood it but I'm realizing I don't remember as much as I thought from that physics class a couple years ago in which we talked about rainbows on CDs briefly haha. I remember distinctly the buzzword "path differences." So it's constructive and destructive interference with the waves that somehow causes the light to separate out into a rainbow? Yeah, I still don't quite get it. Do you have a little more information to help me understand?

    The fact that the light doesn't have to pass through to be diffracted is boggling my mind. What is happening to the light? Is the reflection of the light somehow getting diffracted and creating the rainbow? That is so cool!

      I think the shapes in the chocolate cause waves of particular light to be amplified and others to be absorbed depending on what direction you look at it. For example blue butterfly wings are often not blue but actually have small ridges similar to the holo chocolate.
