With 2 sachets of 120 g of monoammonium phosphate, this set
allows you to grow crystals of about 5 cm, so beautiful that you'll
be happy to keep them carefully in your mineral
collection. The crystals will be blue, yellow, green, or transparent.
Thanks to the 2 experiments offered, the child will understand that very
little is needed to change the crystallization phenomena because no two are alike.
