Supersaturated

A supersaturated solution is one in which the saturation point, at which no more material will dissolve, has been exceeded. This can occur because the saturation point becomes higher as the temperature of the solution is increased. When you dissolve the material at a high temperature and then cool the solution, the material sometimes doesn't crystallize out because the molecules don't know how. They require something to get them started, a seed crystal, or a grain of dust or even a sudden scratch or tap on the surrounding glass.

He walked to the water tap to cool the solution but never got there. Before his eyes, as he walked, he saw a star of crystalline material in the solution appear and then grow suddenly and radiantly until it filled the entire vessel. He saw it grow. Where before was only clear liquid there was now a mass so solid he could turn the vessel upside down and nothing would come out. The one sentence "I hope you are teaching Quality to your students" was said to him, and within a matter of a few months, growing so fast you could almost see it grow, came an enormous, intricate, highly structured mass of thought, formed as if by magic.

What idea is supersaturating your mind? What will be the scratch in the glass that starts crystallization?
