Dr. Saar's AP Chemistry Class: he dissolved around 80 grams of sodium acetate into a small volume of hot water and cooled it so it was extremely supersaturated. In this video he is pouring out the solution onto a glass square that has a few sodium acetate crystals on it. Because it is so supersaturated, the liquid crystallizes upon touching the crystals. As it is poured it forms a stalactite-shaped structure, although it looks like water!
