The two ingredients needed are
-some type of crystal source (magnesium sulfate, table salt, sugar, copper sulfate, etc.)
-water (not sure if other liquids would work, I would imagine they would.)
take any amount of water, and put it in a glass container (beaker, glass, etc)
add your crystal source to the water. stir and keep adding in more of the crystal source until no more dissolves. when 5 minutes have gone by without the crystals dissolving any more, you now have a saturated solution.
now, heat the solution. this can be done in the microwave, on the stove, on a Bunsen Burner, or even on a grill if you want. Just make sure it still stays in the glass container.
when the solution begins to boil, keep adding more of the crystal source, constantly stirring it, until no more crystals dissolve. (<=== make sure you keep the solution on the heat source the entire time you do this step)
allow the solution to cool. when it's cooled to room temperature, you now have a super saturated solution!
THE CHEMISTRY BEHIND THIS--
in summary, water absorbs crystals. heated water absorbs more crystals. when heated, the water absorbs ALOT more crystals than normal, so when it cools the water is TOO full of crystals, making it unstable and able to crystallize very quickly.

Heat the solution
To make a supersaturated solution, you would first dissolve the maximum amount of solute in the solvent at an elevated temperature to increase solubility. Then, slowly cool the solution down without disturbing it to prevent the excess solute from precipitating out, creating a supersaturated solution.
No, evaporation will most likely make the solution supersaturated
The solute will eventually fall out of a supersaturated solution
The solute will eventually fall out of a supersaturated solution
To make a supersaturated solution of CdI2, you would first dissolve an excess amount of CdI2 in hot water until no more can dissolve. Then, allow the solution to cool slowly without disturbing it to prevent crystallization. Once cooled, you will have a supersaturated solution of CdI2 ready for use.
It just makes saltwater. However, you can make a supersaturated liquid by heating it, then slowly cooling it.
Supersaturated
To get a supersaturated solution you can either cool down the solution or let some of the water evaporate. To begin, make some Epsom salt crystals. These are easy to grow and you will begin to see crystals in a couple of hours. Start with one cup of warm distilled water (not boiling).
A solution become supersaturated when the limitt of solute solubility at a given temperature is exceeded.
Adding more solute the solution become supersaturated.
A supersaturated solution has a concentration of solute greater than the solubility at a specific temperature.
