Excuse me, how to preserve this underwater botanical garden?

The colorless and transparent liquid in the glass sink is not water, but an aqueous solution called sodium silicate (people call it water glass). Small particles of various colors are small crystals of several water-soluble colored salts, such as ammonium dichloride, copper sulfate, ferric sulfate, ferrous sulfate, zinc sulfate and nickel sulfate. These small crystals react with sodium silicate to form purple sub-rhombic silicate, blue copper silicate, reddish brown iron silicate, light green ferrous silicate, dark green nickel silicate and white zinc silicate. The reaction between these small crystals and sodium silicate is a very unique and interesting chemical reaction. When these small crystals are put into a glass jar, a water-insoluble silicate film is immediately formed on their surfaces, and this colored film covers the surfaces of the crystals. However, this kind of membrane has a strange temper, which only allows water molecules to pass through and shuts out molecules of other substances. When water molecules enter this film, small crystals are dissolved by water, and high-concentration salt solution is generated in the film, which generates high pressure and makes the film expand until. The colored salt solution in the membrane flows out and reacts with sodium silicate to form a new membrane. Water seeps into the film again, and the film bulges and breaks again ... 6 Every time this cycle is carried out, the branches and leaves of the flower grow a new section. In this way, it only takes a moment to form an underwater garden with lush foliage and blooming flowers. Bring it with the sink.
