Most often, by preparing a saturated solution of a substance in a solvent in which the solubility of the substance increases with temperature, then lowering the temperature while taking care to avoid agitation of or the intrusion of solids into the solution.
A supersaturated solution is most likely to produce crystals if disturbed, as the excess solute in the solution will start to come out of the solution and form crystal structures. Disturbing the solution can provide the necessary energy for the crystallization process to begin.
How a saturated solution can become supersaturated?
To prepare a supersaturated solution of potassium nitrate in water, you would first dissolve an excess amount of potassium nitrate in hot water, stirring continuously until no more of the salt can dissolve. Then, let the solution cool slowly without disturbing it, which will allow the excess salt to form crystals at the bottom, creating a supersaturated solution above it.
Heating the solution increases the solubility of the solute, allowing more of it to dissolve. This creates a supersaturated solution, where the solution is holding more solute than it normally can at that temperature. Upon cooling, the excess solute remains in solution, resulting in a supersaturated solution.
The solute will eventually fall out of a supersaturated solution
A supersaturated solution is when there is more solute present in the solution than can be absorbed by the solvent. When it is disturbed, all of the solute that is not in solution falls out, sometimes forming crystals.

The solute can re-form as a solid.
A supersaturated solution is most likely to form crystals as it cools.
The solution is supersaturated. This means it contains more solute than it would normally hold at the given temperature. Agitation causes the excess solute to come out of solution and form a precipitate.
Adding more solute the solution become supersaturated.
Supersaturated
A solution become supersaturated when the limitt of solute solubility at a given temperature is exceeded.
The addition of a crystal to an aqueous solution can act as a seed for the precipitation of solute particles out of the solution through a process known as crystallization. This occurs when the crystal provides a surface onto which the solute particles can adhere and form a solid precipitate, causing them to come out of the solution.
A supersaturated solution is most likely to produce crystals if disturbed, as the excess solute in the solution will start to come out of the solution and form crystal structures. Disturbing the solution can provide the necessary energy for the crystallization process to begin.
A supersaturated solution has a concentration of solute greater than the solubility at a specific temperature.
