Blooming Garden

   Tools: beaker, glass rod, tweezers, spoon

   Chemicals: glass of water (aqueous solution of Na 2 SiO 3 ), copper sulfate, potassium heptahydrate, nickel sulfate pentahydrate, cobalt sulphate heptahydrate, magnesium sulphate heptahydrate, ferric sulfate or other soluble metal salts

   Procedure: into a beaker or better in a glass container (a small aquarium) pour a solution of water glass and dilute 1:1. Then the container toss in different places few crystals of the above salts. Crystals are seeds from which soon begin to grow beautiful flowers of various colors.

Na 2 SiO 3 + MeSO 4 -> MeSiO 3 + Na 2 SO 4         

   All beauty is nothing but the result of double reaction between the water and glass metal sulfates. Crystals soluble salt gradually dissolves and double entry formed by the reaction insoluble silicates.
