I know my periodic table pretty well, but I may need some help figuring out what these molecules are! Thankfully, FractalSpin spelled it all out in the captions for me: caffeine, dopamine, estrogen, acetylcholine, and serotonin (my fave). All made out of sterling silver, these necklaces replicate each corresponding molecule for you to don, and show off your high level of taste and geekiness. But would you in fact wear any of these? My guess is hell yes.
