9 Genius Halloween Costumes For Science Nerds

6. Iron Man

So, you left it a bit late, huh?

No worries, there's a last minute costume that's arguably smarter than the much more labour-intensive Stark Industries version.

In case you're interested, the chemical symbol for iron is Fe because it derives from the latin word ferrum, whereas the word "iron" is a proto-germanic word. Iron wasn't identified and named by a single person, we've known about it since ancient times, so it gets the best of both worlds.

Something for the science nerds, something for the Marvel nerds and something for the language nerds. Everybody wins.
