You know the trope: an epic fantasy world with magic materials that have strange properties or give people superpowers or what have you. It seems half of the time, this material is a type of crystal with some kind of electric power, and the other half of the time it's a type of metal that's basically steel, but stronger or something. The main examples that come to mind are Marvel, where you have the Soul Stones, Adamantium, and Vibranium.

Are there any other cool types of materials to use for this type of resource? Like maybe an obscure type of material that certain scientists study, but the general public doesn't know much about?

Hello, I would like people to try and find the following:

• An image of someone using a bag phone that is not a stock photo, or an advertisement photo, or a photo from reference websites (such as Wikipedia).

• A recipe that is being presented as an original, or family secret, that is actually the recipe on the back of a box or otherwise publicly known (cannot be a reference to the Friends episode). I will allow personal anecdotes (no points will be awarded, this would just be for my amusement).

• An idea that is published for something that was later patented or otherwise protected under IP, that was published BEFORE the patented time, and the person is not the patent/IP holder. This is a two part find, because you must present the IP as well as the previously published idea.

Those are the only ones I have on the top of my head, I'm open to other people adding "find me" type things, in the same spirit, which is fun.

Please spoiler your results so that others can try it out, before seeing yours.
