Here’s the latest addition to the Loom’s science tattoo collection: from a food scientist, the molecule capsaicin, which makes chiles spicy.

To see all the new tattoos, check out my Flickr set. And keep them coming–either in the comment thread here, or emailed directly to me.

If you crave more science tattoos–not just on the body, but of the body, check out an awesome collection of anatomical tattoos. (Thanks to Steve)
