video How to Demonstrate a Supersaturated Solution ... once you have formed the crystal from the supersaturated solution you can heat it to remove the water molecules from the trihydrate. once this happens it will no longer resemble a crystal at least not macroscopically and will instead resemble a powder.

When you add one more crystal to a supersaturated solution (one in which there's more than the "maximum possible" amount of solute dissolved - due to altered temperature, pressure, etc.), the added crystal provides a surface against which other randomly-moving particles of solute ("extra" particles) can form the shape...
