Diy Water Stone Experiment Kit Magic Garden Sodium Silicate Growth Stones Garden Science Experiment Plastic Material

Description: Metal salts react chemically with sodium silicate solution to form insoluble silicates It will first form a semi-permeable film on the surface of metal salts and crystals that is difficult to dissolve in dry water. This film only allows water to penetrate into the crystals, while ions cannot penetrate in. When the infiltrated water dissolves the soluble salts and cracks the film, it will encounter the sodium silicate to form a new film. This process is repeated to make the metal salt grow into a beautiful water garden. It takes about 2 hours for the growth stone to "grow" completely. The water temperature and the dosage of the growth solution will affect the duration of the experiment. It is recommended to use warm water to dissolve the growth solution better.
