Like throwing a bottle into the sea. It's an S.O.S! We are finding out that it's not the best way to save anybody! Bluebottles in bottles. Commun Bluebottles (Ceruleum Petroleum) or even the more rare Rutilus Petroleum. Just a wee bit of plastic that becomes an elegant mutated jellyfish, enchanting, so délicate and airy. Beware better keep it under control and try to hunt them to extinction.
