Fun Fact
BuzzFeed published a report claiming that Tumblr was utilized as a distribution channel for Russian agents to influence American voting habits during the 2016 presidential election in Feb 2018.
In honor of Moon Landing Day, I'm considering buying some lunar regolith simulant. Real moon rocks are in, shall we say, limited supply, but you can buy Earth-made stuff that is nearly indistinguishable from the real deal from the University of Central Florida. It's not cheap, something like fifty or sixty bucks per kilo for the good stuff, well over a thousand per kilo for the REALLY good stuff, and they don't sell it by the gram (you can get 100g of the really good stuff, or 10g of the crap stuff), so you'll really want to think it over before committing. It's mostly bought by universities to study the effects of sandblasting their instruments with Moon dust or Mars dust, but I think it would be neat to have a jar full of the stuff as a paperweight. It's a high fidelity facsimile, which is up my alley, but I don't know if I want it enough to justify the price tag. $60 is close to a week worth of food for me, so maybe I'll save up and get some for Christmas instead, just in time for Apollo 17's Moon Landing Day (December 11).
