Instant Crystals

The video tutorial explains the process of crystallization, focusing on how sodium ethanoate can form crystals rapidly. It begins with an introduction to crystal formation, followed by a step-by-step guide to preparing a supersaturated solution. The demonstration shows how adding a small amount of solid sodium ethanoate to the solution causes rapid crystallization, forming a stalagmite structure. The tutorial also covers the concept of supersaturation and its practical applications, such as in hand warmers, where a disturbance in the solution leads to an exothermic reaction that generates heat.
