The procedure is simple:
Heat some water and fill the cup halfway. Then add the monoammonium phosphate to the water and stir well until it dissolves completely. Finally, add the stones on which the crystals will form and leave the cup to stand still for a few days (at least 2 weeks). Watch the crystal gradually grow in the container.
The experiment will help you to understand the process by which monoammonium phosphate settles on the pebbles resulting in the formation of crystal structures.
