Growing Crystals Science Experiment [work] -

To grow crystals using a super-saturated solution and observe their formation.

Heat-safe glass jar, string, pencil or popsicle stick, and a pot for boiling water. Optional: Food coloring for aesthetic appeal. 3. Step-by-Step Procedure

Twist a pipe cleaner into a shape (star, heart, or spiral). Tie it to a string, then tie the string to a pencil.

When hot water holds more dissolved solid (supersaturated), cooling causes the solid to come out of solution and attach to surfaces — forming orderly crystal lattices.
