Have you ever wondered what would happen if you ate thermal paste? I'm not sure, but I can advise you that you really, really shouldn't. YouTuber mryeester looks to have been having similar thoughts, as they've endeavoured to create the world's first truly edible thermal paste—and the secret ingredient is gold.
Gold is known for being an excellent conductor of heat, and being in position of a surprising amount of 24-carat gold leaf, mryeester picked it out as the edible thermal transfer element. Yes, you can eat it, as you'll find if you go to a very fancy restaurant. You'll also likely find a large bill at the end of the evening, as the stuff isn't cheap.
