After an artist's feces bottled for your delectation in a "fragrant" dilution and the simulated scent of a woman's orgasmic ecstasy (by a top perfumer no less), the next project involves real sweat. Tamer, you'd say. Apparently not that original though!
There's already a product sold (and another one) that mimics at least the look of sweat beads. Not to mention that we sometimes do drink a sorta diluted "fake-sweat" drink when engaging in sports.
