Kissing may look good and feel sexy, but it turns out the end result looks somewhat like an evil alien slug, bent on world conquest.
Artist Charlie Murphy held a "kiss-in" for Valentine's Day at London's Science Museum, in which she made glass sculptures showing the insides of couples' mouths when they kissed. Murphy put dental alginate into the couples' mouths, and then made them keep kissing for 90 seconds, until the alginate hardened. Romantic! Sexy! And then she made the alginate into glass sculptures resembling brain-eating parasites. She's been doing these "kiss-in" experiments for eight years, and aims to collect 100 of these sculptures, at which point they'll infiltrate the water supply and start taking over the population.
