Growing Mineral Tubes Three dimensional hierarchical materials are widespread in nature but are difficult to synthesize by using self‐assembly/organization. Centimeter‐long ∼100 μm diameter tubes with complex mineral wall structures have been obtained by using a gel–liquid interface through a growth mechanism akin to that of chemical gardens: the tubes grew into alkaline solutions of anions, such as PO 4 3− or CO 3 2− , layered on top of a gelatin gel loaded with metal cations due to the strongly driving chemical reactions across the interface.
