Addition of CaCl2 into a highly alkaline phosphate buffer results in the generation of submerged transparent chemobrionic bubbles mimicking jellyfish that are stable and malleable. A compartmentalized O2‐generating reaction triggered the growth of regular vertical chemical gardens from the bubble through a gas micro‐rocket propelled mechanism. The bubbles can mechanically separate to yield two daughter bubbles in a process reminiscent of cytokinesis or natural jellyfish regeneration, and then re‐grow through new injection of CaCl2. Finally, loading of E. coli bacteria genetically engineered to exert green fluorescence inside the bubbles was demonstrated in a biomimetic analogue of "symbiosis". [ABSTRACT FROM AUTHOR]
