Hannah Fry should be EVERYWHERE!
Her podcast with Adam Rutherford is just gold. Secret Genius should be essential educational material. She's so amazed with this cool stuff that you just get caught up in this vortex of wowness.

I've done this with the "U" in my passport, but I'd like to do it properly. I can see diffraction grating sheets available here but none that say they're food safe or indeed have good reviews. Would love to know where this one was sourced.

what is the sheet called as I've google holographic sheets and holographic foil but don't find the right thing.

why do Brits say "Walla" instead of "Voila"?
Interesting physics, but I'd be very suspicious about putting anything imprinted onto a plastic sheet into my mouth - let alone any food in prolonged contact with hot plastic
