Chemistry in a Nutshell

Learn what diffraction gratings are and see me use one to get chocolate to reflect white light as a rainbow. (This method should also work on other shiny, stampable materials.)

This is the diffraction grating that I used. Note that it is NOT labeled as food grade, so I do not condone eating the chocolate or whatever else you melt onto it: https://www.amazon.com/Robs-Super-Happy-Fun-Store/dp/B00SK3S6BY/?&_encoding=UTF8&tag=chemnut-20&linkCode=ur2&linkId=ceced7d9f74f602f54356fef83ceefa2&camp=1789&creative=9325
