Chemical garden - Wikipedia

A chemical garden is an experiment in chemistry usually performed by adding metal salts, such as copper sulfate or cobalt(II) chloride, to an aqueous solution of sodium silie (otherwise known as waterglass). This results in the growth of plant-like forms in minutes to hours.[1][2] [3] [4] The chemical garden was first observed and described
