These photographs by Frederic Fontenoy are of blood and milk mixing together. Yep. It actually makes a whole lot of sense when you think about the differing consistencies of those two fluids: one sticky and slightly coagulated, the other considerably less so. They duel together nicely, taking turns giving way, their colors blending so beautifully, or not blending at all. And for the record (oh, you better believe I checked), yes, blood is thicker than milk.
